Abstract:
1. A damper disk assembly comprising: a pair of first circular disk members being affixed to and axially opposing each other; a second circular disk member being arranged between said pair of first circular disk members, said second circular disk member being rotatable relative to said pair of first circular disk members; first elastic members being configured to connect elastically said first circular disk members with said second circular disk member in a rotating direction; second elastic members being configured to connect elastically said first circular disk members with said second circular disk member in the rotating direction, said second elastic members having a lower rigidity than said first elastic members, said second elastic members being arranged between said first elastic members in the rotating direction; pin members being configured to affix said pair of first circular disk members together, said pin members being provided on an outer periphery of said second circular disk member to form torsional angle stoppers to limit relative rotation between said first circular disk members and said second circular disk member, radial positions of said torsional angle stoppers being outward that of said second elastic members, said pin members being movable radially outside of and relative to said second elastic members; and a positive side of torsion characteristics including,
