PROBLEM TO BE SOLVED: To provide an antimotion device comprising a passive type damper which can preferably attenuate vibration even when vibration angular speed of a vibration attenuation object is small.SOLUTION: An antimotion device comprises: a base 20 which is fixed to a vibration attenuation object; a gimbal 40 which is supported rotatably around a first axis RA; a damper mechanism 30 which attenuates relative rotation motion of the gimbal 40 to the base 20; and a fly wheel 50 which can rotatable around a second axis RB vertical to the first axis RA. The damper mechanism 30 is a passive type damper mechanism. A first value of a damping coefficient of the damper mechanism 30 when angular speed of the gimbal 40 is first angular speed is larger than a second value of a damping coefficient of the damper mechanism 30 when the angular speed of the gimbal 40 is second angular speed which is smaller than the first angular speed.SELECTED DRAWING: Figure 3

    【課題】減揺対象物の揺動角速度が小さい場合でも、当該揺動を好適に減衰することが可能なパッシブ型ダンパを備える減揺装置を提供する。【解決手段】減揺装置は、減揺対象物に固定されるベース20と、第1軸RAまわりに回転自在に支持されるジンバル40と、ベース20に対するジンバル40の相対回転運動を減衰させるダンパ機構30と、第1軸RAに垂直な第2軸RBまわりに回転自在なフライホイール50とを具備する。ダンパ機構30は、パッシブ型のダンパ機構である。また、ジンバル40の角速度が第1角速度である時のダンパ機構30のダンピング係数の第1値は、ジンバル40の角速度が第1角速度より小さな第2角速度である時のダンパ機構30のダンピング係数の第2値よりも大きい。【選択図】図3
