ABSTRACT:
In a friction clutch a first disc-shaped driving member and a second disc-shaped driving member are held in frictional contact by a spring so that the driving members rotate coaxially, each driving member has a facing surface directed toward the other. Rolling members are positioned between the facing surfaces and seat in opposed indentations when the driving members rotate as a unit. When a predetermined torque is exceeded, the biasing action of the spring is overcome and the driving members move away from one another in the axial direction. During such axial displacement, the rolling members move out of at least the indentations in one of the driving members and aid in the separation of the driving members.
