Claims (1)

[Scope of utility model registration request] In a flywheel device having a first flywheel fixedly attached to a crankshaft of an engine, and a second flywheel attached to the first flywheel so as to be relatively rotatable, one of the first and second flywheels is provided. At least one flywheel that is attached to the engine and moves together in the direction of rotation, is slidably pressed against the other flywheel by a constantly acting biasing force, and is coupled to the other flywheel by centrifugal force at a predetermined engine speed or higher. 1. A flywheel device comprising: a facing member, the facing member comprising a plate substrate and a friction plate joined to the plate substrate.
