Abstract
A clutch having an outer member, an inner member mounted in the outer member, a cage interposed between the outer and inner members and cam elements movably mounted in pockets formed in the cage. Torque-setting elastic members are provided between the cage and one of the inner and outer members so that while the torque on the elastic member is smaller than a preset value, they will rotate in unison with some clearance left therebetween in the direction of rotation. When the torque on the elastic member gets larger than the preset value, the elastic member deforms to allow the cage to turn relative to the member engaged therewith. Now, the cam elements are pushed by the cage into engagement with both cam surfaces formed on the inner periphery of the outer member and the outer periphery of the inner member, thus brining the two members into engagement.
