Abstract
A torque fluctuation absorbing apparatus including a limiter mechanism includes: a disc member connected to one of the driving-side member and the driven-side member, a first plate and a second plate connected to the other one of the driving-side member and the driven-side member; a frictional member fixed to the disc member and interposed between the first plate and the second plate, the frictional member including a frictional surface slidably in contact with the first and second plates. The frictional member includes a fibrous substrate and is formed with a plurality of grooves at the frictional surface. A minimum dimension between two adjacent grooves from among the plurality of grooves is designed to be greater than or equal to 2 mm and smaller than or equal to 7 mm.
