Abstract
A flywheel assembly that receives torque from a crankshaft of an engine includes a flywheel, a damper mechanism, and a frictional resistance generation mechanism. The damper mechanism elastically connects the flywheel to the crankshaft in a rotational direction. The damper mechanism includes an input member, an output member, elastic members to connect elastically the input member and the output member in the rotational direction. The frictional resistance generation mechanism is located functionally in parallel with the damper mechanism in the rotational direction. The frictional resistance generation mechanism utilizes a portion of the flywheel as a friction surface.
