A torque fluctuation absorbing apparatus absorbs torque fluctuations occurring in a torque transmission pathway from an input side rotating member to an output side rotating member. The apparatus includes: a vibration absorbing member in which elastic members are coupled in series, and which absorbs torque fluctuations; circular outer contour plates coupled to the input side rotating member, and disposed to be spatially separated from one another in an axial direction of the output side rotating member; a hub member including a boss section coupled to the output side rotating member, and a flange section provided on the boss section and disposed between the outer contour plates; and a circular intermediate plate disposed between the flange section and the outer contour plates, coupled between the elastic members, and transmitting a torque from one elastic member to another elastic member.

Torque fluctuation absorbing apparatus

A damper device includes a first member, a second member, an elastic member and a supporting member. The first member has two wall members separated from each other. The supporting member includes projections (preventing portion) that make contact with one of two wall portions (wall members) so as to prevent the supporting member and an elastic member from being inclined (falling, rotationally moving) in the axial direction.

Damper device

A damper includes a first, second, and third rotation member rotatable around a rotation axis, a first elastic portion interposed between the first rotation member and the second rotation member and elastically deformed by a relative rotation between the first rotation member and the second rotation member, a second elastic portion interposed between the second rotation member and the third rotation member and elastically deformed by a relative rotation between the second rotation member and the third rotation member, and a dynamic vibration absorber. The dynamic vibration absorber includes a rolling element that is positioned at an inner side relative to the first elastic portion and the second elastic portion in a radial direction of the rotation axis, and is rotatable relative to the second rotation member.

Damper

A damper apparatus includes a first rotation member, a second rotation member, a first elastic portion interposed between the first and the second rotation members and elastically deformed by a relative rotation between the first and the second rotation members, a third rotation member, a second elastic portion interposed between the second and third rotation members and elastically deformed by a relative rotation between the second and third rotation members, and a dynamic vibration absorber. The dynamic vibration absorber includes an anchor member and a third elastic portion that is interposed between the anchor member and the second rotation member and that is elastically deformed by a relative rotation between the anchor member and the second rotation member. At least the third elastic portion is positioned at an inner side of the first elastic portion and the second elastic portion in a radial direction of the rotation axis.
