ABSTRACT:
In a damping force adjusting structure of a hydraulic shock absorber in which a part of an oil liquid is introduced to a back pressure chamber provided in a back surface side of a damping valve from a back pressure introduction path, a pressure within the back pressure chamber is leaked from a leak path, and a damping force can be adjusted by controlling a valve opening pressure of the damping valve by controlling the pressure in the back pressure chamber. A leaf valve with slit is provided in the back pressure introduction path, and a slit provided in the leaf valve with slit is formed as an introduction side orifice.
