To provide a pressure buffer device or the like which can stably obtain a skyhook effect.SOLUTION: A pressure buffer device comprises: a piston which defines the inside of a cylinder, and in which a flow passage for allowing the circulation of fluid is formed; a rod for holding the piston at one end part, connected to a vehicle body at the other end part, and formed with an internal space in which the fluid can circulate, and a communication hole which can make the flow passage and the outside of the piston communicate with each other via the internal space; and a moving member which is relatively movable to the rod in an axial direction of the rod, arranged in the internal space so that one end face and the other end face in the axial direction coincide with each other in pressure, and moved so as to block the communication hole accompanied by the acceleration of a vertical motion of the vehicle body.SELECTED DRAWING: Figure 2
【課題】安定してスカイフック効果を得ることができる圧力緩衝装置等を提供する。【解決手段】シリンダ内を区画するとともに流体が流通する流路が形成されたピストンと、一方の端部にピストンを保持するとともに他方の端部が車体に連結され、流体が流通可能な内部空間と、内部空間を介して流路とピストンの外部とを連通可能な連通孔が形成されたロッドと、ロッドの軸方向にロッドに対して相対的に移動可能であって軸方向の一方の端面と他方の端面とが同圧となるように内部空間内に配置され、車体の上下動の加速度に伴い連通孔を閉じるように移動する移動部材と、を備える圧力緩衝装置。【選択図】図2
