Abstract:
1. A clutch device for transmitting and stopping torque from a crankshaft of an engine to a transmission, comprising: a flywheel being movable in an axial direction relative to the crankshaft within a certain range, and having a friction surface on an axial side opposite to the engine; a damper mechanism being configured to connect elastically said flywheel with the crankshaft, said damper mechanism having elastic members; a clutch disk assembly having a frictional connection portion adjacent to said friction surface of said flywheel; a clutch cover assembly being attached to said flywheel to bias elastically said frictional connection portion against said friction surface of said flywheel; a release device being configured to release the bias toward said frictional connection portion by applying a load to said clutch cover assembly; a bending direction support mechanism being configured to support elastically said flywheel, said flywheel being movable in a bending direction; and a bending direction movement suppression mechanism being configured to suppress bending movement of said flywheel by connecting said flywheel to a crankshaft side member when said clutch cover assembly receives said load toward the engine in said axial direction, said crankshaft side member having a radially inner cylindrical portion extending in an axial direction being configured to support a radially inner facing surface of a plate attached to said damper mechanism and said flywheel.
