PROBLEM TO BE SOLVED: To provide a vibration reduction device capable of preferably changing over an attenuation force in response to a value of vibration to be inputted.SOLUTION: This invention relates to a vibration reduction device A for reducing a relative vibration between the two members relatively vibrated. The vibration reduction device comprises a cylinder 5 of which one end is connected to one member and arranged, a piston 8 for defining an inside part of the cylinder 5 into a first cell 6 and a second cell 7, a piston rod 9 with one end being connected to the piston 8, extended outside in an axial line direction of the cylinder 5 and the other end being connected to the other member and arranged and working fluid 10 filled in the first cell 6 and the second cell 7 and there is provided a variable attenuation mechanism 20 for increasing an attenuation coefficient when it exceeds a prescribed reaction.SELECTED DRAWING: Figure 2
【課題】入力される振動の大小に応じて好適に減衰力を切替えることが可能な振動低減装置を提供する。【解決手段】相対振動する二部材の間の相対振動を低減させるための振動低減装置Ａであって、一端を一方の部材に接続して配設されるシリンダー５と、シリンダー５の内部を第１隔室６と第２隔室７に区画するピストン８と、ピストン８に一端を接続してシリンダー５の軸線方向外側に延設され、他端を他方の部材に接続して配設されるピストンロッド９と、第１隔室６及び第２隔室７に充填される作動流体１０とを備えるとともに、予め設定した所定の反力を超えると減衰係数を増加させる可変減衰機構２０を備える。【選択図】図２
