There is provided a structure for limiting the rotational range of a manual plate in an automatic transmission, which is capable of making the manual plate shareable among a plurality of types of automatic transmissions differing in the number of gear positions. In the case where the manual plate is applied to a 5-position automatic transmission, the height of a case-side drive range direction stopper that limits the rotational range of the manual plate is set such that an end of a check plate is fitted into five notches ranging from a parking range notch to a low range notch. In the case where the manual plate is applied to a 4-position automatic transmission, the height of a case-side drive range direction stopper that limits the rotational range of the manual plate is set such that the end of the check plate is fitted into four notches ranging from the parking range notch to a drive range notch. As a result, the manual plate can be shared between the 4-position and 5-position automatic transmissions, and the kinds of parts can be reduced.
