In a hydraulic shock absorber equipped with a reservoir tank for storing hydraulic oil,
A pressure-side damping valve that provides resistance to the flow of hydraulic oil from the piston-side oil chamber to an oil passage connecting the piston-side oil chamber and the reservoir tank, and a first check valve that allows the flow of hydraulic oil from the reservoir tank. A separate oil passage is provided on the reservoir tank side of these valves and connected to the piston rod side oil chamber via a second check valve that allows the flow of hydraulic oil from the oil passage. A hydraulic system characterized in that a rebound damping valve is interposed to allow the flow of hydraulic oil from the oil chamber to the piston side oil chamber, and the compression damping valve is provided with an adjusting means that can adjust the damping force from the outside. buffer. The brief description of the drawing has been amended as follows. The phrase "third check valve" in the first line of page 11 of the specification is corrected to read "rebound damping valve."
