ABSTRACT:
A flywheel assembly that transmits torque from a crankshaft of an engine is provided. The flywheel assembly has a flywheel with a friction surface and an elastic coupling mechanism. The elastic coupling mechanism elastically couples the flywheel and the crankshaft in a rotating direction, and has a pair of first disk-shaped members axially spaced from each other and fixed together, a second disk-shaped member that is arranged between the pair of first disk-shaped members, and an elastic member that elastically couples the first disk-shaped members to the second disk-shaped member in the rotating direction. Further, a plate-like coupling portion extending between outer peripheries of the paired first disk-shaped members fixes the pair of first disk-shaped members together.
