とを特徴とする油圧緩衝装置。[Claims for Utility Model Registration] A piston is provided in a cylinder, the piston defines two oil chambers in the cylinder, a hollow piston rod is fixed to the piston, and an oil passage formed in the piston rod defines two oil chambers in the cylinder. In a hydraulic shock absorber that communicates two oil chambers, an orifice is formed in the first oil passage, a rod made of a material with a higher coefficient of thermal expansion than the piston rod is arranged in the hollow part of the piston rod, and at the tip of the rod, A hydraulic shock absorber characterized in that a needle valve is provided which moves due to thermal expansion of the rod and faces into the orifice.
