  • Patent number: 6913538
    Abstract: In a torque transmission system, plural engagement pieces elastically deformable are formed integrally with an outer peripheral portion of a circular portion of a center hub to be engaged with an inner periphery portion of a pulley. A bridge portion of the center hub is disposed to be broken when a torque large than a predetermined torque is applied there to. Since the engagement protrusion pieces are engaged with a part of the pulley, it can prevent the center hub from being removed and falling when the bridge portion of the center hub is broken.
