PCT No. PCT/JP87/00978 Sec. 371 Date Aug. 2, 1988 Sec. 102(e) Date Aug. 2, 1988 PCT Filed Dec. 14, 1987.A clutch cover assembly, in which a radially inner side spring force action point (an inside projection 44, for example) of a lever 40 is provided at a position radially inward from an outer peripheral edge 33 of a diaphragm spring 30. A radially outer side spring force action point (an outside projection 46) of the lever 40 is positioned at a distance B between a rotation center O1 of the lever 40 and the outer side spring force action point shorter than a distance A between the rotation center O1 and the inner side spring force action point. The lever 40 is adapted to multiply a spring force P of the diaghragm spring 30. The reaction force action point of the diaphragm spring 30 is shifted to an outer peripheral part of the clutch cover 16, so that a deflection of the clutch cover 16 is reduced and a release efficiency is improved.
