Zusammenfassung:A forward and rearward motion switching device to be used in an automatic transmission system for a vehicle, comprises a planetary mechanism provided with an input element, an element to be fixed and an output element which are disposed coaxially and are rotatable relative to each other, the planetary mechanism outputting a rotational driving force of an internal combustion engine transmitted to the input element as a rotational driving force in the reverse direction to the rotation of the input element from the output element through the input element, the element to be fixed and the output element, and a brake capable of fixing the element to be fixed of the planetary mechanism. The brake comprises a rotational drum which is integrally formed with the element to be fixed and has an outer peripheral surface, and a brake band that surrounds the outer peripheral surface of the rotational drum to fix the same.
