圧緩衝器。Equipped with an oil chamber that has a sealed air chamber and an oil reservoir chamber, and whose internal pressure changes depending on the stroke position, and a valve device that changes the damping force according to the pressure generated in the oil chamber. In a hydraulic shock absorber, the valve device includes a relief spring whose one end is locked to a cylinder end member, and a relief valve which is biased to close a part of the flow path through the relief spring and includes a deflection valve. and a variable orifice provided in a flow path behind the relief valve, thereby making it possible to adjust the initial load of the relief valve.
