In the above hydraulic shock absorber, the oil chamber is divided into an upper oil chamber and a lower oil chamber by a piston inserted into a cylinder, and an oil passage hole is formed in the piston to communicate the upper and lower oil chambers. An oil passageway communicating with the upper and lower chambers of the piston is formed in the shaft hole of the piston rod that protrudes from the piston and projects from one end of the cylinder, and the orifice formed in the middle of the oil passageway is connected to the shaft hole of the piston rod that protrudes from one end of the cylinder. The tip of the needle valve located in the shaft hole of the piston rod is made to face each other, and one end is slidably and airtightly connected to the tip of the bushing rod inserted into the shaft hole. A thermal expansion chamber formed in the fitting part is sealed with a thermal expansion liquid or gas, and the other end of the bushing rod is connected to the outer end of the piston rod. A hydraulic shock absorber characterized by being engaged with an adjustment nut screwed onto a rod side.
