摘要： A damper apparatus according to an embodiment includes a pair of first plates, a second plate, an elastic member, a first friction material and a second friction material. The elastic member is configured to elastically deform in a circumferential direction of a rotation axis by a relative rotation between the pair of first plates and the second plate around the rotation axis. The first friction material is configured to generate a first friction torque in a case where the second plate rotates relative to the pair of first plates in a first direction from an initial state. The second friction material is configured to generate a second friction torque greater than the first friction torque in a case where the second plate rotates relative to the pair of first plates in a second direction which is opposite from the first direction from the initial state.

摘要： A torque fluctuation absorber includes a first plate member to which power of rotation is transmitted from a first rotational shaft, a second plate member arranged at a preset distance from the first plate member, a third plate member arranged between the first plate member and the second plate member and configured to transmit power of rotation to a second rotational shaft. The torque fluctuation absorber also includes a fourth plate member arranged at a preset distance from the second plate member, and a resilient member arranged between the second plate member and the fourth plate member and configured to bias the second plate member towards the third plate member. The fourth plate member includes a fulcrum point that supports a mid portion of the resilient member.

摘要： 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.

摘要： A damper device includes: a pressing plate; a rotation plate disposed to oppose the pressing plate; an elastic member elastically linking the pressing and rotation plates, and in which bending is generated when relative twist of the pressing and rotation plates is generated; and seats provided on both end surfaces of the elastic member The seat has a projected surface, the pressing plate has a recessed surface corresponding to the projected surface, the seats and the pressing plate come into surface-contact with each other in a case where the relative twist is not generated, one seat and the pressing plate come into surface-contact with each other, and a void is formed between the other seat and the pressing plate, in a case where the relative twist is generated, and the void increases as an angle of the relative twist increases.

摘要： 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.
