A higher portfolio turnover rate may<br />indicate higher transaction costs and may result in higher taxes when fund shares <br />are held in a taxable account. These costs, which are not reflected in annual fund <br />operating expenses or in the example, affect the fund's investment results. During <br />the most recent fiscal year, the fund's portfolio turnover rate was 57% of the <br />average value of its portfolio.</tt> <div style="display:none">~ http://www.americanfunds.com/role/ExpenseExample_S000013585Member column dei_LegalEntityAxis compact * column rr_ProspectusShareClassAxis compact * row primary compact * ~</div> <div style="display:none">~ http://www.americanfunds.com/role/BarChartData_S000013585Member column dei_LegalEntityAxis compact * column rr_ProspectusShareClassAxis compact * row primary compact * ~</div> <tt>The fund's investment objective is to provide you with current income,<br />consistent with the maturity and quality standards described in this<br />prospectus, and preservation of capital.</tt> <tt>This example is intended to help you compare the cost of investing in<br />the fund with the cost of investing in other mutual funds.<br /> <br />The example assumes that you invest $10,000 in the fund for the time periods<br />indicated and then redeem all of your shares at the end of those periods. The<br />example also assumes that your investment has a 5% return each year and that <br />the fund's operating expenses remain the same.</tt> <tt>The fund will invest at least 80% of its assets in bonds (bonds include any debt<br />instrument and cash equivalents). The fund maintains a portfolio having a<br />dollar-weighted average maturity no greater than three years and consisting<br />primarily of debt securities rated AA- or Aa3 or better by Nationally Recognized<br />Statistical Rating Organizations designated by the fund's investment adviser or<br />unrated but determined to be of equivalent quality by the fund's investment<br />adviser. The fund may invest up to 10% of its assets in debt securities in the A<br />rating category or in unrated securities determined by the fund's investment<br />adviser to be of equivalent quality.<br /> <br />The fund primarily invests in short-term debt securities denominated in U.S.<br />dollars, including securities issued and guaranteed by the U.S. government,<br />securities of corporate issuers, mortgage-backed securities and debt securities<br />and mortgage-backed securities issued by government sponsored entities and<br />Federal agencies and instrumentalities that are not backed by the full faith and<br />credit of the U.S. government. The fund may also invest in asset-backed<br />securities (securities backed by assets such as auto loans, credit card<br />receivables or other providers of credit).<br /> <br />The investment adviser uses a system of multiple portfolio counselors in<br />managing the fund's assets. Under this approach, the portfolio of the fund is<br />divided into segments managed by individual counselors who decide how their<br />respective segments will be invested.<br /> <br />The fund relies on the professional judgment of its investment adviser to make<br />decisions about the fund's portfolio investments. The basic investment<br />philosophy of the investment adviser is to seek to invest in attractively priced<br />securities that, in its opinion, represent good investment opportunities. The<br />investment adviser believes that an important way to accomplish this is by<br />analyzing various factors, which may include the credit strength of the issuer,<br />prices of similar securities issued by comparable issuers, anticipated changes<br />in interest rates, general market conditions and other factors pertinent to the<br />particular security being evaluated. Securities may be sold when the investment<br />adviser believes that they no longer represent relatively attractive investment<br />opportunities.</tt> Short-Term Bond Fund of America ® You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $500,000 in American Funds. Example After-tax returns are calculated using the highest individual federal income tax rates in effect during each year of the periods shown and do not reflect the impact of state and local taxes. Investment objective Past investment results (before and after taxes) are not predictive of future investment results. The Lipper Short Investment Grade Debt Funds Average includes the fund and other funds that disclose investment objectives and/or strategies reasonably comparable to the fund's objective.

You may lose money by investing in the fund. The<br />likelihood of loss may be greater if you invest for a shorter period of time.<br /> <br />Market conditions - The prices of, and the income generated by, the securities<br />held by the fund may decline due to market conditions and other factors,<br />including those directly involving the issuers of securities held by the fund.<br /> <br />Investing in bonds - Rising interest rates will generally cause the prices of<br />bonds and other debt securities to fall. Longer maturity debt securities may be<br />subject to greater price fluctuations than shorter maturity debt securities. In<br />addition, falling interest rates may cause an issuer to redeem, call or<br />refinance a security before its stated maturity, which may result in the fund<br />having to reinvest the proceeds in lower yielding securities.<br /> <br />Bonds and other debt securities are subject to credit risk, which is the<br />possibility that the credit strength of an issuer will weaken and/or an issuer<br />of a debt security will fail to make timely payments of principal or interest<br />and the security will go into default.<br />&#xA0;&#xA0;<br />Investing in mortgage-backed and asset-backed securities - Many types of bonds<br />and other debt securities, including mortgage-backed securities, are subject to<br />prepayment risk as well as the risks associated with investing in debt<br />securities in general. If interest rates fall and the loans underlying these<br />securities are prepaid faster than expected, the fund may have to reinvest the<br />prepaid principal in lower yielding securities, thus reducing the fund's income.<br />Conversely, if interest rates increase and the loans underlying the securities<br />are prepaid more slowly than expected, the expected duration of the securities<br />may be extended, reducing the cash flow for potential reinvestment in higher<br />yielding securities.<br /> <br />Investing in securities backed by the U.S. government - Securities backed by the<br />U.S. Treasury or the full faith and credit of the U.S. government are guaranteed<br />only as to the timely payment of interest and principal when held to maturity.<br />Accordingly, the current market values for these securities will fluctuate with<br />changes in interest rates. Securities issued by government-sponsored entities<br />and federal agencies and instrumentalities that are not backed by the full faith<br />and credit of the U.S. government are neither issued nor guaranteed by the U.S.<br />government.<br /> <br />Management - The investment adviser to the fund actively manages the fund's<br />investments. Consequently, the fund is subject to the risk that the methods and<br />analyses employed by the investment adviser in this process may not produce the<br />desired results. This could cause the fund to lose value or its investment<br />results to lag relevant benchmarks or other funds with similar objectives.<br /> <br />Your investment in the fund is not a bank deposit and is not insured or<br />guaranteed by the Federal Deposit Insurance Corporation or any other<br />governmental agency, entity or person. You should consider how this fund fits<br />into your overall investment program.</tt> Fees and expenses of the fund After-tax returns are shown only for Class A shares; after-tax returns for other share classes will vary.

Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock This table describes the fees and expenses that you may pay if you buy and hold
shares of the fund. You may qualify for sales charge discounts if you and your
family invest, or agree to invest in the future, at least $500,000 in American
Funds. More information about these and other discounts is available from your
financial professional and in the "Sales charge reductions and waivers" section
on page 26 of the prospectus and on page 60 of the fund's statement of
additional information.

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio turnover
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate may
indicate higher transaction costs and may result in higher taxes when fund shares
are held in a taxable account. These costs, which are not reflected in annual fund
operating expenses or in the example, affect the fund's investment results. During
the most recent fiscal year, the fund's portfolio turnover rate was 57% of the
average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal investment strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The fund will invest at least 80% of its assets in bonds (bonds include any debt
instrument and cash equivalents). The fund maintains a portfolio having a
dollar-weighted average maturity no greater than three years and consisting
primarily of debt securities rated AA- or Aa3 or better by Nationally Recognized
Statistical Rating Organizations designated by the fund's investment adviser or
unrated but determined to be of equivalent quality by the fund's investment
adviser. The fund may invest up to 10% of its assets in debt securities in the A
rating category or in unrated securities determined by the fund's investment
adviser to be of equivalent quality.

The fund primarily invests in short-term debt securities denominated in U.S.
dollars, including securities issued and guaranteed by the U.S. government,
securities of corporate issuers, mortgage-backed securities and debt securities
and mortgage-backed securities issued by government sponsored entities and
Federal agencies and instrumentalities that are not backed by the full faith and
credit of the U.S. government. The fund may also invest in asset-backed
securities (securities backed by assets such as auto loans, credit card
receivables or other providers of credit).

The investment adviser uses a system of multiple portfolio counselors in
managing the fund's assets. Under this approach, the portfolio of the fund is
divided into segments managed by individual counselors who decide how their
respective segments will be invested.

The fund relies on the professional judgment of its investment adviser to make
decisions about the fund's portfolio investments. The basic investment
philosophy of the investment adviser is to seek to invest in attractively priced
securities that, in its opinion, represent good investment opportunities. The
investment adviser believes that an important way to accomplish this is by
analyzing various factors, which may include the credit strength of the issuer,
prices of similar securities issued by comparable issuers, anticipated changes
in interest rates, general market conditions and other factors pertinent to the
particular security being evaluated. Securities may be sold when the investment
adviser believes that they no longer represent relatively attractive investment
opportunities.
Risk [Heading] rr_RiskHeading Principal risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock This section describes the principal risks associated with the fund's principal
investment strategies. You may lose money by investing in the fund. The
likelihood of loss may be greater if you invest for a shorter period of time.

Market conditions - The prices of, and the income generated by, the securities
held by the fund may decline due to market conditions and other factors,
including those directly involving the issuers of securities held by the fund.

Investing in bonds - Rising interest rates will generally cause the prices of
bonds and other debt securities to fall. Longer maturity debt securities may be
subject to greater price fluctuations than shorter maturity debt securities. In
addition, falling interest rates may cause an issuer to redeem, call or
refinance a security before its stated maturity, which may result in the fund
having to reinvest the proceeds in lower yielding securities.

Bonds and other debt securities are subject to credit risk, which is the
possibility that the credit strength of an issuer will weaken and/or an issuer
of a debt security will fail to make timely payments of principal or interest
and the security will go into default.
  
Investing in mortgage-backed and asset-backed securities - Many types of bonds
and other debt securities, including mortgage-backed securities, are subject to
prepayment risk as well as the risks associated with investing in debt
securities in general. If interest rates fall and the loans underlying these
securities are prepaid faster than expected, the fund may have to reinvest the
prepaid principal in lower yielding securities, thus reducing the fund's income.
Conversely, if interest rates increase and the loans underlying the securities
are prepaid more slowly than expected, the expected duration of the securities
may be extended, reducing the cash flow for potential reinvestment in higher
yielding securities.

Investing in securities backed by the U.S. government - Securities backed by the
U.S. Treasury or the full faith and credit of the U.S. government are guaranteed
only as to the timely payment of interest and principal when held to maturity.
Accordingly, the current market values for these securities will fluctuate with
changes in interest rates. Securities issued by government-sponsored entities
and federal agencies and instrumentalities that are not backed by the full faith
and credit of the U.S. government are neither issued nor guaranteed by the U.S.
government.

Management - The investment adviser to the fund actively manages the fund's
investments. Consequently, the fund is subject to the risk that the methods and
analyses employed by the investment adviser in this process may not produce the
desired results. This could cause the fund to lose value or its investment
results to lag relevant benchmarks or other funds with similar objectives.

Your investment in the fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
governmental agency, entity or person. You should consider how this fund fits
