。[Claims for Utility Model Registration] (1) A piston rod is movably inserted into the cylinder via a piston, the piston partitions two oil chambers within the cylinder, and the piston rod has a passage that communicates the two oil chambers. A hydraulic shock absorber is provided with a needle valve movable up and down in the middle of the passage, and the needle valve is driven vertically from the outside via a control rod to adjust the opening area of the passage. It consists of a hollow body, a center rod connected to the body, a rotary rod in which the control rod is rotatably inserted into the piston rod, and a rotary rod which is fitted into the rotary rod in an odd shape and is vertically and rotatably inserted into the piston rod. It consists of a hollow adjusting screw that is screwed together so that it can move in any direction, and the base end of the needle valve is inserted into the adjusting screw so that it can move up and down, and there is a small hole in the axial direction that allows two oil chambers to pass through the center rod. , a radial hole, and a large hole provided in series with the small hole, and the needle valve is guided and inserted into the large hole, and the valve body of the needle valve is movable to open and close in the seat of the small hole. A damping force adjustment device for a hydraulic shock absorber, characterized in that it is inserted. (2) The damping force adjusting device for a hydraulic shock absorber according to claim 1, wherein the needle valve is guided in the axial direction by a guide provided in the body of the needle valve.
