To easily adjust damping force in a hydraulic shock absorber.

In this hydraulic shock absorber 110, an outer cylinder 111 is rotatably arranged on the outer periphery of an inner cylinder 112, orifice passages 151A to 151D mutually different in the opening area are formed in different positions on the same circumference in a stroke range of a piston 122 in the inner cylinder 112, a sleeve 160 is rotatably slidingly contacted with the outer periphery of the inner cylinder 112 so as to block up these orifice passages, this sleeve 160 is provided with an opening 161 for selectively communicating with one of the orifice passages on the same circumference and communicating a piston side oil chamber 123B and a reservoir chamber 131, and the sleeve 160 is fixed to the outer cylinder 111.
