In a hydraulic shock absorber, the leaf valve has a leaf valve arranged at the outlet end of the port so as to be openable and closable, and the leaf valve is a very low speed leaf valve and a leaf valve with an orifice superimposed on the bottom surface of the very low speed leaf valve. The outer periphery of the leaf valve is held between the lower end seat surface of the piston and the spring seat biased by a spring, and the inner periphery of the leaf valve forms an arbitrary gap with the outer periphery of the guide provided inside the piston. A damping valve for a hydraulic shock absorber, characterized in that the damping valve is supported so as to be flexible. (2) A piston rod is movably inserted into the cylinder via a piston, the piston partitions two oil chambers in the cylinder, a port is formed in the piston to communicate the two oil chambers, and the outlet end of the port is In a hydraulic shock absorber in which a leaf valve is arranged to freely open and close, the leaf valve is composed of a very low speed leaf valve and a leaf valve with an orifice stacked on the top surface of the very low speed leaf valve, and the outer periphery of the leaf valve is The inner periphery of the leaf valve with an orifice is fixed, and the inner periphery of the leaf valve for very low speeds is attached to the outer periphery of a guide provided inside the piston. A damping valve for a hydraulic shock absorber, characterized in that it is supported flexibly while forming an arbitrary gap.
