Abstract:
1. A damper disk assembly comprising: a pair of first and second plate-like rotating members being fixed to each other; a third plate-like rotating member being disposed between the pair of first and second plate-like rotating members in an axial direction; an elastic member coupling the pair of first and second plate-like rotating members and the third plate-like rotating member in the rotational direction; and a friction plate being disposed to operate in parallel with the elastic member between the pair of first and second plate-like rotating members and the third plate-like rotating member in the rotational direction, the friction plate frictionally engaging with the pair of first and the second plate-like rotating members, and engaging with the third plate-like rotating member to be relatively rotatable only in a torsional angle, the torsion angle being in a range between 0.1 to 5 degrees relative to an axis of rotation of the damper disk assembly.
