Patent ID: 8257183

Claim:
A torque fluctuation absorber comprising: a first plate member to which rotation power from a first rotating shaft is transmitted; a substantially ring-shaped second plate member and third plate member to which rotation power from the first plate member is transmitted; a fourth plate member located between the second plate member and the third plate member, wherein the fourth plate member transmits rotation power to a second rotating shaft; a resilient member that absorbs torque fluctuation between the second or third plate members and the fourth plate member; wherein the first plate member is located on the opposite side of the fourth plate member from the second plate member, wherein the first plate member rotates in unison with the second and third plate members; a predetermined member on a power transmission path between at least two of the first, second and third plate members has a stopper section, wherein 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, and by contacting to the fourth plate member, prevents relative rotation between the second or third plate member and the fourth plate member; the stopper section is a component of the first plate member; and the first plate member is formed such that a portion that corresponds to the stopper section is bent and located on an orbit of a predetermined portion of the fourth plate member.
