あるのを「伸側減衰弁」と補正する。[Claim for Utility Model Registration] A piston connected to a piston rod is housed in a cylinder so as to be freely slidable, thereby defining a piston side oil chamber and a piston rod side oil chamber. 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 in 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.
The extension side is connected to the piston rod side oil chamber through a second check valve that allows the flow of hydraulic oil from the oil passage, and allows the flow of hydraulic oil from the piston rod side oil chamber to the piston side oil chamber. A hydraulic shock absorber, characterized in that a damping valve is interposed therein, a suspension spring is externally mounted on the shock absorber body, and means is provided for increasing the set load of the compression side damping valve in accordance with the load of the suspension spring. The brief description of the drawing has been amended as follows. The phrase "third check valve" in the third line of page 13 of the specification is corrected to read "rebound side damping valve."

油圧緩衝器。 A piston with a piston rod connected to the cylinder is slidably housed to define a piston-side oil chamber and a piston rod-side oil chamber, while a reservoir tank stores hydraulic oil that is displaced as the piston operates outside the cylinder. In a hydraulic shock absorber equipped with
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. The oil passages on the reservoir tank side of these valves are connected to the piston rod side oil chamber via a second check valve that allows the flow of hydraulic oil from the oil passage, and the piston rod side oil is connected to the piston. A third check valve that allows the flow of hydraulic oil from the chamber to the piston side oil chamber is interposed, a suspension spring is externally mounted on the shock absorber body, and the pressure side damping valve is set according to the load of the suspension spring. A hydraulic shock absorber characterized by being provided with means for increasing the load.
