Claims

[Scope of utility model registration request]

The wheel side tube is slidably inserted into the vehicle body side tube, the damper cylinder stands up from the bottom of the wheel side tube, the piston rod is movably inserted into the damper cylinder via the piston, and the damper cylinder and the vehicle body side tube are inserted. In a hydraulic shock absorber in which a suspension spring is interposed between the tube and the upper part of the tube, a cap is provided at the upper part of the tube on the vehicle body side, and a nut is screwed into the inner periphery of the cap so as to be movable up and down. A guide groove is formed along the axial direction, and the lower part of the nut supports one end of the suspension spring directly or through a spacer, and an adjuster connected to the piston rod is rotatably inserted into the inner periphery of the nut. The upper part of the adjuster is connected to the dial, and a guide protrusion provided on the body of the adjuster is fitted into the guide groove so as to be movable in the axial direction, and a push rod is screwed into the inside of the adjuster so as to be movable up and down. A hydraulic shock absorber characterized in that the push rod is interlocked with a control rod for adjusting a valve provided within the piston rod.
