A flywheel device for a prime mover can be made compact in axial size and has an effectively increased inertial mass. The flywheel device includes a drive plate and a mass ring. The drive plate has an annular projection and is attached to a crankshaft concentric with the crankshaft. The mass ring has an annular recess and is concentrically attached to the drive plate by the annular recess being fitted on the annular projection of the drive plate. The flywheel device transmits torque from an engine as the prime mover to the input shaft of an automatic transmission while reducing variation in the torque.
