PROBLEM TO BE SOLVED: To improve a degree of freedom of the adjustment of an attenuation force of a pressure buffer device.SOLUTION: In a hydraulic pressure buffer device 1, a cylinder 11 for storing oil is arranged. A piston member 30 which is arranged so as to be movable to an axial direction of the cylinder 11, and partitions a space in the cylinder 11 into a first oil chamber Y1 and a second oil chamber Y2 is arranged. A reservoir chamber R which is located outside the cylinder 11 in a radial direction of the cylinder 11, and in which oil is accumulated accompanied by the movement of the piston member 30 is arranged. Furthermore, a communication path L which is located outside the reservoir chamber R in the radial direction of the cylinder 11, and which makes the first oil chamber Y1 and the second oil chamber Y2 communicate with each other is arranged.SELECTED DRAWING: Figure 1 【課題】圧力緩衝装置の減衰力の調整の自由度を向上させる。【解決手段】油圧緩衝装置１には、オイルを収容するシリンダ１１が設けられている。さらに、シリンダ１１の軸方向に移動可能に設けられ、シリンダ１１内の空間を第１油室Ｙ１と第２油室Ｙ２とに区画するピストン部材３０が設けられている。さらに、シリンダ１１の径方向においてシリンダ１１よりも外側に位置し、ピストン部材３０の移動に伴いオイルが溜まるリザーバ室Ｒが設けられている。また、シリンダ１１の径方向においてリザーバ室Ｒよりも外側に位置し、第１油室Ｙ１と第２油室Ｙ２とを連絡する連絡路Ｌが設けられている。【選択図】図１
