ABSTRACT:
The clutch cover assembly comprises a clutch cover, a pressure plate, a fulcrum ring, a diaphragm spring, and a diaphragm spring posture maintenance mechanism. The maintenance mechanism includes an adjustment mechanism which is composed with a pair of wedge mechanisms inclined surfaces of which extend in the circumferential direction and keep in contact with each other, and a spring for urging one of the wedge mechanisms against the other in the circumferential direction so as to move either one of the wedge mechanisms in the axial direction. Since adjustment mechanism functions by the circumferential wedge mechanisms, it is possible to accurately maintain the diaphragm spring posture without being affected by the engine rotation speed.
