Abstract
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. The predetermined member on a power transmission path between at least two of the first, second and third plate members has a stopper section. The stopper section allows relative rotation between the second or third plate member and the fourth plate member within a predetermined distance in the circumferential direction of the second plate member. The stopper section prevents relative rotation between the second or third plate member and the fourth plate member by contacting to the fourth plate member.
