As shown in FIG. 2, these openings 21 c and 21 d are configured as through holes that overlap each other in the axial direction, for example. In the openings 21 c and 21 d, the first elastic member 23 is disposed between the edge on one side and the edge on the other side in the circumferential direction of the second rotating member 26. The side plates 21a and 21b, that is, the outer member 21, can be made of, for example, a metal material.

  As shown in FIG. 2, the inner member 22 has, for example, a center plate 22a. The center plate 22a is positioned between the side plate 21a and the side plate 21b of the outer member 21, and is separated from the side plate 21a and the side plate 21b in the axial direction. The center plate 22a is formed in an annular plate shape around the rotation center Ax and extends in the radial direction of the second rotation member 26. The center plate 22a is provided so as to be relatively rotatable around the rotation center Ax with respect to the side plates 21a and 21b of the outer member 21. However, the relative rotation between the center plate 22a and the side plates 21a and 21b is limited to a predetermined angle range by, for example, contact of stoppers (not shown). The center plate 22a is provided with an opening 22b. The opening 22b is configured as, for example, a notch that opens toward the outside in the radial direction of the center plate 22a with respect to the radial direction of the second rotating member 26. Further, the opening 22b penetrates the center plate 22a in the axial direction.

The center plate 22a, that is, the inner member 22, can be made of, for example, a metal material.

  The first elastic member 23 shown in FIGS. 1 and 2 is a coil spring made of, for example, a metal material and extending substantially along the circumferential direction of the second rotating member 26. The first elastic member 23 is accommodated in the openings 21c and 21d and the opening 22b that are axially overlapped with each other.

The first elastic member 23 is elastically contracted by the edges. Conversely, in a state where the openings 21c and 21d and the opening 22b are elastically shrunk, with respect to the circumferential direction of the second rotating member 26, one edge in the circumferential direction of the openings 21c and 21d and the opening 22b. The first elastic member 23 is elastically extended when it is relatively rotated in a direction away from the other edge in the circumferential direction. That is, the first elastic member 23 is sandwiched between the side plates 21a and 21b of the first rotating member 25 and the center plate 22a of the second rotating member 26, and is relatively rotated around the rotation center Ax. Accordingly, the elastic member elastically expands and contracts along the circumferential direction of the second rotating member 26. The first elastic member 23 elastically contracts to store torque as a compressive force, and elastically extends to release the compressive force as torque. Thus, the first elastic member 23 is positioned between the first rotating member 25 and the second rotating member 26, and the second rotating member 26 and the second rotating member 26 are connected to the second rotating member 26. It is sandwiched substantially along the circumferential direction of the rotating member 26 and elastically expands and contracts along the circumferential direction of the second rotating member 26.

For example, the hooking portion 24f is a state in which an elastic member (not shown) that expands and contracts with the relative rotation between the inner member 22 and the hub member 24 is elastically contracted. It can be configured to be caught in the circumferential direction. The damper part 12 can relieve torque fluctuations by expansion and contraction of the elastic member.

The second elastic member 33 is coupled to the base member 31 and the weight member 32 by, for example, vulcanization adhesion. Note that the second elastic member 33 may be coupled to the base member 31 and the weight member 32 via an intervening member such as a collar, for example.

  In the dynamic vibration absorber 13, for example, when vibration is generated in the second rotating member 26, the weight member 32 is accompanied by the elastic deformation of the second elastic member 33, and is opposite to the vibration direction of the second rotating member 26. By vibrating (moving), the vibration of the second rotating member 26 can be attenuated.
