Abstract
A clutch apparatus including a compressive force boosting member for biasing a presser plate in a direction to compress friction plates between a pressure bearing plate and the presser plate upon accelerated rotation of a clutch inner member. A movable cam member is formed independently wherein the machinability thereof is enhanced. A compressive force boosting member includes a cam mechanism. The movable cam member is separate from a clutch inner member and a movable spring retainer member for movement independent of said clutch inner member in response to accelerated rotation of the clutch inner member. A pressure bearing plate is fixed to a clutch inner member rotatable relatively to an output shaft. A plurality of bosses extending through a presser plate have respective ends affixed thereto. A back torque limiter member has a cam mechanism disposed between a clutch inner member and an output member.
