Flywheel for internal combustion engine

摘要

A flywheel for an internal combustion engine includes a flexible plate (2) connected to a crankshaft (1) of the engine. A mass member (5) is connected to the flexible plate. A clearance (7) is formed at an axially outer portion (2b) with respect to a connecting portion of the flexible plate to the crankshaft. A spring member (10) is disposed in the clearance such that both ends of the spring member being in contact with clearance defining surfaces of the flexible plate and the mass member, respectively. This flywheel enables the prevision of the spring member without increasing a thickness of an installing portion to the crankshaft. <IMAGE>
