Abstract
A clutch disk assembly 1 includes an output rotary member 4, an intermediate member 3, first springs 7, a damper 8, plates 12 and 13, and third springs 5. The intermediate member 3 is disposed radially outside the output rotary member 4. The first springs 7 are arranged between the output rotary member 4 and the intermediate member 3, and are circumferentially compressed when a hub and the intermediate member 3 rotate relatively to each other in a first stage of relative rotary displacement. A damper 8 is disposed between the output rotary member 4 and the intermediate member 3, and includes second springs 10 that are not compressed in the first stage of relative rotary displacement but are compressed in a second stage of relative rotary displacement. The torsion angle corresponding to the second stage is larger than a torsion angle corresponding to the first stage. The plates 12 and 13 are arranged on the axial side of the intermediate member 3. The third springs 5 circumferentially and elastically couple the intermediate member 3 to the plates 12 and 13. The above configuration suppresses a jumping phenomenon between the first and second stages.
