A driven pulley system for use in a torque converter of a vehicle is disclosed. The driven pulley system includes a motion-transmitting fixed unit and a belt-tensioning movable unit. The fixed unit is arranged to be fixed to a rotatable output shaft of the vehicle for rotation therewith to transmit motion between the output shaft and a belt included in the torque converter and includes a fixed flange and a cam. The belt-tensioning movable unit is arranged for movement relative to the fixed unit and includes a movable flange and a cam follower. The fixed flange and the movable flange cooperate to receive the belt therebetween for engagement therewith. The movable flange includes a rotation limiter arranged to engage the cam to limit rotation of the cam relative to the cam follower in a second direction opposite to the first direction.
