The clutch disk includes a pair of friction facings 15a and 15b and a cushioning plate 16. The cushioning plate 16 includes in a fixing part 16a, a plurality of first installation parts 16b, a plurality of second installation parts 16c, a plurality of first connecting parts 16d, and a plurality of second connecting parts 16e. The first installation parts 16b have first friction facings 15a installed thereon. The first installation parts 16b with their first friction facings 15a extend from the fixing part 16a to an outer circumferential side of the cushioning plate 16. The second installation parts 16c have second friction facings 15b installed thereon. The second installation parts 16c with their second friction facings 15b are disposed between the first installation parts 16b in a circular direction in a location different from that of the first installation parts 16b in an axial direction. The first connecting parts 16d connect one of the ends of the first and second installation parts 16b and 16c together in a circular direction.
