DAMPER DEVICE

To provide a novel damper device capable of generating friction resistance between a first rotation element and a second rotation element and a support member regardless of rotation speed when the damper device is rotated, and capable of suppressing increase in the friction resistance when the damper device is rotated at relatively high rotation speed.SOLUTION: A damper device includes a first rotation element, a second rotation element, an elastic element, and a pair of support members. A sliding surface of the support member slides on a third support surface of the second rotation element. A first support surface of the first rotation element restricts rotation of the support member with respect to the first support surface. A second support surface of the second rotation element restricts rotation of the support member with respect to the second support surface. There is a gap between the first support surface and a first facing surface when the first rotation element and the support member are relatively rotated, and there is a gap between the second support surface and a second facing surface when the second rotation element and the support member are relatively rotated.SELECTED DRAWING: Figure 8 【課題】ダンパ装置の回転時において回転数の高低に関わらず第１回転要素および第２回転要素と支持部材との間に摩擦抵抗を生じさせることができるとともに、ダンパ装置の比較的高回転時には当該摩擦抵抗が大きくなるのを抑制することができる新規なダンパ装置を得る。【解決手段】ダンパ装置は、第１回転要素と、第２回転要素と、弾性要素と、一対の支持部材と、を備える。支持部材の摺動面は、第２回転要素の第３支持面を摺動する。第１回転要素の第１支持面は、第１支持面に対する支持部材の回転を制限する。第２回転要素の第２支持面は、第２支持面に対する支持部材の回転を制限する。第１回転要素と支持部材とが相対回転している場合に、第１支持面と第１対向面との間に隙間が有り、第２回転要素と支持部材とが相対回転している場合に、第２支持面と第２対向面との間に隙間が有る。【選択図】図８
