Patent ID: 8465372

Claim:
A torque fluctuation absorber, comprising: a flywheel fixed on a first rotating shaft by a fixation member, a damper unit connected with a second rotating shaft and for absorbing fluctuation of a torque occurred between the first rotating shaft and the second rotating shaft by elastic force, a limiter unit provided on a power transmission path between the flywheel and the damper unit, wherein the limiter unit induces a slide when the fluctuation of the torque exceeded a predetermined value, and a predetermined member rotating with the first rotating shaft on a power transmission path between the first rotating shaft and the limiter unit, wherein the predetermined member has a guide portion that prevents movement of the damper unit in a transverse direction to a rotating axis, and wherein the guide portion is provided at radially internal side of the fixation member, the predetermined member being a guide member made of an elastic body which is fixed on the first rotating shaft, wherein the damper unit comprises a plate member connected to the limiter unit, and a hub member connected to the second rotating shaft, and the guide portion contacts both the plate member and the hub member and prevents movement of both the plate member and the hub member in a direction transverse to the rotating axis.
