ブソ、−バ。The shock absorber has a hydraulic fluid reservoir chamber between an inner cylinder and an outer cylinder coaxially arranged with a spaced distance between them on the outside of the inner cylinder, and the mounting fitted to the outer cylinder is connected to the cylinder. or a diaphragm having upper and lower ends fixed to the inner circumferential surface of the outer cylinder and defining a fluid chamber in the reservoir chamber in combination with the inner circumferential surface, the fluid chamber being supplied with pressurized fluid; a diaphragm that is in close contact with the outer circumferential surface of the inner cylinder to partition the reservoir chamber into upper and lower parts; a bypass pipe that opens into the reservoir chamber above the upper end of the diaphragm and below the lower end of the diaphragm; a check valve installed in the bypass pipe and allowing the flow of hydraulic fluid only from the reservoir chamber above the diaphragm to the reservoir chamber below; and a pressurizing means for supplying pressure fluid.
