To provide a damper for vehicle which can simultaneously achieve reduction of a load on a damper mount upon input of an excess load, an improvement of the behavior stability of the vehicle by highly responsive impact absorption, and an improvement of riding comfort by blocking input of high-frequency low-load.SOLUTION: A damper for a vehicle comprises: a movable member which linearly moves according to a load input from wheel side; a conversion member for converting the linear movement of the movable member to rotational movement; an electric motor having a rotor which rotates in conjunction with the rotational movement converted by the conversion member; a motor housing accommodating the electric motor; and a damper mount housing fixed to a vehicle body and connected with the motor housing via a first elastic member. The damper attenuates the linear movement of the movable member with an electromagnetic force of the electric motor. At least either of the motor housing and the damper mount housing is provided with a second elastic member which abuts on the other side when the motor housing and the damper mount housing approach each other along with by an input of a load.SELECTED DRAWING: Figure 3

    【課題】過荷重入力時のダンパーマウントへの荷重負荷低減と、即応性の高い衝撃吸収による車両の挙動安定性向上と、高周波低荷重入力の遮断による乗り心地向上とを両立できる車両用ダンパーを提供する。【解決手段】車輪側からの荷重入力に応じて直線運動する可動部材と、可動部材の直線運動を回転運動に変換する変換部材と、変換部材によって変換された回転運動に連動して回転するロータを有する電動モータと、電動モータを収容するモータハウジングと、車体に固定されて第1の弾性部材を介してモータハウジングと接続されるダンパーマウントハウジングとを備え、可動部材の直線運動を電動モータの電磁力によって減衰させる車両用ダンパーであって、モータハウジング及びダンパーマウントハウジングの少なくともいずれか一方に、荷重の入力に伴ってモータハウジングとダンパーマウントハウジングとが近接した場合に他方側に当接する第2の弾性部材を有する。【選択図】図3
