Patent ID: 7195111

Claim:
A clutch device for releasably transmitting a torque from a crankshaft of an engine to a transmission, comprising: a flywheel being axially movable within a predetermined range with respect to the crankshaft, and having a first friction surface on a side remote from the engine, and a second friction surface on a side facing the engine; a damper mechanism elastically coupling said flywheel and said crankshaft together in a rotating direction; a clutch disk assembly having a frictional coupling portion neighboring to said first friction surface of said flywheel; a clutch cover assembly attached to said flywheel being configured to bias elastically said frictional coupling portion toward said first friction surface of said flywheel; a release device releasing a biasing force from said frictional coupling portion by applying a load directed axially toward the engine to said clutch cover assembly; and a relative rotation suppressing mechanism coupling said flywheel to a member on the crankshaft side when said clutch cover assembly receives said load directed axially toward the engine.
