A flywheel assembly having an outer peripheral part of a first flywheel engaged with or disengaged from a clutch disc connected to a crank shaft by a relatively thin connecting plate disposed along an end face of a second flywheel opposite to the clutch disc, an outer periphery supporting mechanism supports a damper inertial part of the second flywheel relative to the first flywheel in a circumferentially rockable manner, a torsion damper mechanism resiliently connects the damper inertial part to a friction damping mechanism is installed in an inner peripheral part of the damper inertial part of the second flywheel, the torsion damper mechanisms are rotatably supported on the crankshaft by a bearing, a pressure surface on which a friction member of the friction damping mechanism presses is formed on a part of the torsion damper mechanism, the friction member being fixed to a substantially annular friction plate axially slidable on a spline hub of the clutch disc and a spring member urging the friction plate and the friction member toward the second flywheel is interposed between the friction plate and the spline hub.
