The continuously variable transmission comprises a hydraulic actuator formed on a back side of a movable sheave to change a belt groove between a fixed sheave and a movable sheave, and a torque cam assembly adapted to convert a torque into an axial thrust force by a relative rotation between a pair of cam members contacted to each other. In the belt-driven continuously variable transmission, a piston fitted onto a shaft of the driven pulley while allowing to rotate relatively therewith and to reciprocate thereon is integrated with one of the cam members of driven side and with an output gear for outputting torque of the pulley. The cam member of drive side is fixed in an axial direction on a driven shaft to be rotated integrally therewith.

Abstract: A translational force Fh to one side in a rotational axis direction is caused to act from a hydraulic piston to a sleeve when an engaged stage between an engagement tooth and an engaged tooth is maintained, so that translation of the sleeve to the other side in the rotational axis direction and consequent disengagement of the engagement tooth and the engaged tooth can be prevented. Therefore, the engaged state between the engagement member and the engaged member can be stably maintained regardless of the condition of the torque acting from the drive source to the engagement member.
