A hydraulic shock absorber is provided with a damping force generating valve mechanism that controls the flow of oil to generate a damping force, wherein the damping force generating valve mechanism is provided to block an oil passage of the piston, and the damping force generating valve mechanism is provided to block an oil passage of the piston. a first disc valve in which a passage is formed facing the oil passage and communicating between the front and back; a second disc valve that comes into contact with the first disc valve and closes the passage; and the second disc valve. a third disc valve disposed at a constant interval with a retainer interposed between the third disc valve, and a third disc valve disposed on the peripheral edge side of the second disc valve and the third disc valve to prevent deflection of the second disc valve. A hydraulic shock absorber comprising: a ring forming an allowable gap; and a passage formed in a third disc valve and communicating the gap and the cylinder chamber.
