ABSTRACT:
In a clutch cover assembly, a regulating mechanism allows a fulcrum ring to move in an axial direction away from a pressure plate in response to wear of a friction facing, but limits amount of movement in accordance with the amount of wear. The regulating mechanism includes a bolt and a bushing. The bolt is fixed to a second side face of the pressure plate and extends axially. The bushing is engaged with the bolt by the friction force. In an alternate embodiment, an urging mechanism of the clutch cover assembly urges a fulcrum ring away from the pressure plate. The fulcrum ring is formed with a plurality of first inclined faces which engage second inclined faces formed on a wedge part. A friction plate is disposed between the pressure plate and the wedge part limiting movement of the wedge part.
