Claims

[Scope of utility model registration request]

An input shaft rotatably supported by a housing and rotationally driven, a sun gear spline-coupled to the input shaft, an output shaft coaxially provided with the input shaft, and an output carrier fixed to the output shaft. The input carrier is rotatably supported by a forward clutch which is connected to and disconnected from the sun gear through a forward clutch having a forward clutch drum fixed to the sun gear, and a pinion shaft installed between both carriers. A planetary gear type forward and backward movement characterized by having a pair of pinions that mesh with a sun gear, a ring gear that meshes with the outer pinion and is rotatably provided with respect to the housing, and a reverse brake that can stop the ring gear. switching device.
