Kind Code:

A1

Abstract:

Provided is a dynamic damper device that occupies a small space in the axial direction and that can be made lightweight. This device comprises a clutch part (28), a driven plate (33), a plurality of torsion springs (29, 32), and a dynamic damper device (34). The dynamic damper device (34) includes a damper plate (52), a pair of inertia rings (53), and a plurality of coil springs (55). The damper plate (52) has a plurality of spring housing parts (52a). The inertia rings (53) are arranged on respective sides, in the axial direction, of the damper plate (52) so as to be rotatable relative to the damper plate (52), and each have spring housing parts (53a). The plurality of coil springs (55) are housed in the respective spring housing parts (52a, 53a), and elastically couple the damper plate (52) and the pair of inertia rings (53).
