Abstract
A torque fluctuation absorbing apparatus absorbing a torsional vibration includes a plate member configured to be provided at a power transmission system and including a rolling guide surface, and a mass member rolling on the rolling guide surface of the plate member. The rolling guide surface includes plural first rolling guide surfaces each formed in an arc shape and provided radially inward relative to an outer circumferential portion of the plate member to be arranged in a circumferential direction and a second rolling guide surface allowing the mass member to roll on a locus which is different from a locus on the first rolling guide surface formed in the arc shape. Loci of the mass member are seamlessly switched from the locus in which the mass member rolls on the first rolling guide surface to the locus in which the mass member rolls on the second rolling guide surface.
