A hydraulic shock absorber comprises a cylinder (11) with an expandable and contractible piston rod (12), an outer casing (13) disposed on the outside of the cylinder (11), and a reservoir (16) defined between the outer casing and the cylinder. Due to an elastically deformable bladder (14) disposed inside the reservoir, a gas chamber (17) in which gas is sealed is formed between the bladder and the outer casing, and a reservoir chamber (18) communicated with the inside of the cylinder and designed for guiding hydraulic fluid is formed between the bladder and the cylinder. Furthermore, a gas sealing valve (23) for opening and closing a flow conduit (24) communicated with the gas chamber provided to part of the outer casing is provided to a bottom portion (19) of the outer casing, and allowing gas to enter and exit the gas chamber via the gas sealing valve makes it possible to freely adjust the gas pressure in the hydraulic shock absorber from the outside.
