Abstract
A clutch disk assembly includes two pieces of friction facings, cushioning plates 12, clutch plate 3, retaining plate 4, a plurality of connecting pins 11, hub and rivets 17. The cushioning plates 12 are disposed side by side in a circular direction between two pieces of friction facings. Each of the cushioning plates 12 includes a cushioning part 16 disposed between two pieces of friction facings, and an installation part 15 in which two holes 15a are formed apart each other in a circular direction. The connecting pins 11 fixedly couple the outer circumferential portions of plates 3 and 4 to each other. The rivets 17 are inserted in the holes 15a to fix the cushioning plates 12 to the outer circumferential edge of the clutch plate 3. The locations of the connecting pins 11 in a circular direction are located between two adjacent holes 15a of the cushioning plates 12 in a circular direction. The locations of the connecting pins 11 reduce the stresses in the installation parts 15 of the cushioning plates 12. At least a part of each of the connecting pins 11 is located farther outwardly in a radial direction than the most inner circumferential edge of the installation parts 15 of each of the cushioning plates 12.
