Abstract
A torque fluctuation absorber includes a first rotating member arranged to be rotatable, a second rotating member arranged in a rotatable manner relative to the first rotating member, a coil spring for buffering a torsion between the first rotating member and the second rotating member by means of an elastic force, and a cushion member arranged at an inside of the coil spring and buffering the torsion between the first rotating member and the second rotating member by means of an elastic force, wherein the cushion member includes an elastic member formed in a columnar shape, and an abrasion resistant member partly covering a side surface of the elastic member and including a greater abrasion resistance than an abrasion resistance of the elastic member.
