PURPOSE:To give a vibration damping property to a flywheel, by coupling a second flywheel damper inertia units with a drive transmission system through a damper by means of a friction damping mechanism only when a first flywheel of a clutch disk is forcibly brought into contact. CONSTITUTION:A connection plate 31 disposed along the edge of a counter clutch disk side of a second flywheel 36 causes the periphery of a first flywheel 32 to be coupled with a crank shaft 30. Further, a bearing 37 is disposed between the damper inertia units 37b of the second flywheel 36 and a flange unit 37 and a forcible contact surface 44 is formed where a friction member 48 of a friction damping mechanism is forcibly brought into contact with the damper inertia unit 37b. The friction member 48 is fixed to a friction plate 50 slidably disposed on a spline hub 35f of a clutch disk 34 a spring 46 is interposed between the friction plate 50 and the spline hub 35f. |
