Patent number: 8257183Abstract: A torque fluctuation absorber includes a first plate member, ring-shaped second and third plate members, a fourth plate member, a resilient member and a predetermined member. The resilient member absorbs torque fluctuation between the second or third plate member and the fourth plate member.
