Abstract

A power transfer device includes a hydraulic clutch capable of coupling and decoupling a secondary shaft of a CVT and axles to and from each other. A secondary pulley of the CVT includes a movable sheave movably supported by the secondary shaft, and a secondary piston that rotates together with the secondary shaft and that constitutes a second hydraulic actuator together with the movable sheave. The secondary piston of the second hydraulic actuator is used to define an engagement oil chamber of the hydraulic clutch.
