Abstract: A cylindrical bushing member includes at least one groove of a depth and width to fully accommodate a coil spring within the inner periphery of the bushing with the spring, when relaxed having an inner diameter slightly larger than the diameter of a shaft member projecting axially therethrough. The coil spring is fixed relative to the bushing so as to be non-rotatable relative thereto. The coil spring has at least one end in contact with the periphery of the shaft for frictional engagement therewith such that relative rotation of the bushing and the shaft in one direction causes multiple turns of the coil spring to engage the periphery of the shaft and to snub the spring and to cause a driving member to rotate a driven member as fast as that of the driving member, but permit the driven member to rotate faster and free-wheel to overrun the driving member. Additional turns of wire of the coil spring may be wrapped about the outer periphery of the bushing within an outer peripheral groove with the free end thereof engaging the outer periphery of the outer peripheral groove wall to snub the outer turns of spring wire to effect a grip between the outer turns of the wire coil spring and the bushing during clutching operation of the clutch.
