DAMPER DEVICE

PROBLEM TO BE SOLVED: To provide a damper device in which an oscillation body can be enlarged.SOLUTION: A damper device comprises: a rotating body which can rotate around a rotation center, and has a first face orthogonal to an axis of the rotation center; an oscillating body which has a second face facing the first face, is attached to the rotating body, and can relatively oscillate to a peripheral direction of an oscillation center with respect to the rotating body; and a limit part which is interposed between the rotating body and the oscillating body, limits the relative oscillation of the oscillating body with respect to the rotating body by being pressed against at least either of the first face and the second face by an elastic force, and separates from at least either of the first face and the second face by a centrifugal force in a state that the rotating body rotates at a speed higher than a prescribed rotational speed.SELECTED DRAWING: Figure 1 【課題】揺動体を大きくすることができるダンパ装置を提供する。【解決手段】実施形態のダンパ装置は、回転中心回りに回転可能であって、前記回転中心の軸に直交する第１の面を有する回転体と、前記第１の面に向く第２の面を有し、前記回転体に取り付けられるとともに、前記回転体に対して揺動中心の周方向に相対的に揺動可能な揺動体と、前記回転体と前記揺動体との間に介在し、弾性力により前記第１の面と前記第２の面との少なくとも一方に押し付けられることによって前記回転体に対する前記揺動体の相対的な揺動を制限するとともに、前記回転体が所定の回転速度より速く回転した状態で遠心力により前記第１の面と前記第２の面との少なくとも一方から離間する、制限部と、を備える。【選択図】図１
