PROBLEM TO BE SOLVED: To adjust the damping force in a partition member generated in accordance with movement in one direction and another direction with a simple configuration.SOLUTION: A pressure buffer device 1 comprises a cylinder for storing liquid, a piston 30 for partitioning into a first liquid chamber Y1 and a second liquid chamber Y2 storing the liquid in a space in the cylinder, a second oil passage 412 formed in the piston 30 and making liquid flowing from the first liquid chamber Y1 to the second liquid chamber Y2 in accordance with movement of the piston 30 in one axial direction flow in a specific direction, a first oil passage 411 and an inversion oil passage 41R for making the liquid flowing from the second liquid chamber Y2 to the first liquid chamber Y1 in accordance with movement in another axial other direction of the piston 30 flow along a specific direction, a damping valve 42 for controlling flow of the liquid in the second oil passage 412 and the first oil passage 411, and load imparting means that imparts a load to the damping valve 42 in a direction in which the damping valve 42 closes the second oil passage 412 and the first oil passage 411 and is capable of varying the load of the damping valve 42. |
