ABSTRACT:
A ring gear support member is supported radially immovably on the outer circumference of an input shaft through a ball bearing. A brake hub of a reverse brake, as supported by the ring gear support member, is made movable in the circumferential direction relative to the ring gear support member and is urged to a center position by a coil spring. When the reverse brake is applied to couple the ring gear support member unrotatably to a casing, the brake hub is supported through the coil spring by the ring gear support member. As a result, the meshing vibration, as generated at the meshing portion between pinions and a ring gear, can be prevented from being transmitted to the casing through the brake hub, thereby reducing noise.
