ABSTRACT:
A flywheel device is provided which includes a drive side flywheel, a driven side flywheel rotatable relative to the drive side flywheel, and a plurality of springs which connect the drive side flywheel and the driven side flywheel on arms defined on the driven side flywheel. The arms are provided so that all springs engage the arms at the same time during acceleration while only some of the springs engage the arms during deceleration. Finally, the deceleration side spring constant of the flywheel device is smaller than the acceleration side spring constant of the flywheel device.
