Abstract
A power transmission device has a first clutch membercoupled to an output member. A second clutch memberhas a plurality of driven-side clutch plates. A back-torque transmitting cam presses the drive-side clutch platesand the driven-side clutch platesagainst each other by moving the second clutch memberwhen a rotational force is input to the first clutch member. A cushioning memberis interposed between the first clutch memberand the second clutch member. The cushioning member, by being compressed, applies an urging force while allowing movements of an interlocking memberand a pressure memberin a process where the interlocking membermoves and the pressure membermoves from the inactive position toward the active position.
