Abstract
A torque fluctuation absorbing apparatus includes a first plate member, a second plate member rotatable relative to the first plate member, and a first friction member disposed between the first plate member and the second plate member and pressed against the first plate member in a slidable manner. The second plate member includes a first retaining surface that makes contact with the first friction member. The first friction member includes a plurality of grooves at a surface facing the first retaining surface of the second plate member, the grooves extending in a radial direction of the first friction member.
