Abstract

A clutch cover assembly comprises a pre-assembled combination of parts including a cover (10) which is fixed in the axial direction and a pressure plate (14) which is movable in the axial direction. A diaphragm spring (11) acts on the pressure plate (14). There are means to limit axial movement of the axially movable part and to retain this part radially. These means comprise a limiting member (50) having at least one inclined surface (44) and a retaining member (47) having at least one edge (49) disposed opposite the aforementioned inclined surface and adapted to immobilize the axially movable part in the storage position of the pre-assembled combination. By virtue of mutual interference, sufficient cohesion is conferred on the assembly to protect its drive straps (23) from damage while in storage.
