Claims

[Claims for Utility Model Registration] 1. An annular clutch cover, an annular fulcrum coaxially supported by the clutch cover, and an axial pressing force supported by the fulcrum and applied to the radially inner circumferential portion. a diaphragm spring whose radially outer circumferential portion is displaceable through the diaphragm spring; and a diaphragm spring which is pressed by the outer circumferential portion of the diaphragm spring and is moved between a predetermined engagement position at the front in the axial direction and a release position at the rear in the axial direction through the clutch operation. one edge of the rivet is abutted and supported via a pressure plate that can be displaced by the clutch cover, and a shoulder portion of the rivet supported by the clutch cover, and the other edge is disposed so as to be able to come into contact with the diaphragm spring; A clutch cover assembly comprising: an annular return spring that exerts an elastic force on the diaphragm spring in a direction to reduce the pressing force when the pressure plate is in a position displaced further forward from the predetermined engagement position. , supported by the rivet and abuts against and supports a radially intermediate portion of the return spring, and prevents displacement of the return spring from the shoulder portion when the pressure plate is in the release position. A clutch cover assembly characterized in that an intermediate abutting member is arranged. 2. The clutch cover assembly according to claim 1, wherein said intermediate abutment member is a washer fixedly supported on another shoulder portion of said rivet. 3. The clutch cover assembly according to claim 1, wherein said intermediate abutment member is an annular plate coaxial with said return spring.
