In a clutch disk assembly 1, first and second flange plates 3 and 4 are disposed between first and second sub-plates 5 and 6. First and second retaining plates 7 and 8 are disposed at opposite sides of a group of the first and second retaining plates 7 and 8 and the flange plates 5 and 6, and are fixed together. First coil springs 9 are disposed axially between the first and second retaining plates 7 and 8. Within a first displacement range of relative rotation between plates 3 and 4 and the plates 7 and 8, both the coil springs 9 and 10 are compressed. Within a second displacement range larger than the first displacement range, the plates 3 and 4 are brought into contact with the second coil springs 10, so that only the second coil springs 10 undergo further compression.
