PROBLEM TO BE SOLVED: To effectively prevent the occurrence of a belt slip in a torque variation absorbing damper which transmits torque while absorbing rotational variation.SOLUTION: A torque variation absorbing damper includes: a hub-side rotary body 1 which is fitted to a rotary shaft and rotates integrally with the rotary shaft; a pulley 2 which is arranged concentrically on the outer peripheral side of the hub-side rotary body 1 and can be displaced relatively to the hub-side rotary body 1 in a circumferential direction; a corrugated sleeve 3 which is provided on one of the outer peripheral surface of the hub-side rotary body 1 and the inner peripheral surface on the pulley 2 side and has a mountain part 3a and a valley part 3b formed alternately in the circumferential direction; circumference-directional stoppers 4a which are provided on the other of the outer peripheral surface of the hub-side rotary body 1 and the inner peripheral surface on the pulley 2 side at the same intervals with mountain parts 3a; and a rolling body 5 which is interposed between respective valley parts 3b of the corrugated sleeve 3 and the other of the outer peripheral surface of the hub-side rotary body 1 and the inner peripheral surface on the pulley 2 side. |
