PROBLEM TO BE SOLVED: To secure the strength and disassembly workability of an inner tube and to secure seal performance of a ring-shaped oil chamber while reducing friction by absorbing the eccentricity of the inner tube and an outer tube caused by a transverse force acting on the lower end of the inner tube in a hydraulic shock absorber which supports the inner tube slidably through a bush fixed to the top and bottom of the inside circumference of the outer tube, which slides a piston of a piston rod attached to the outer tube side into the oil chamber on the inner periphery of the inner tube, and which forms a volume compensation chamber for the portion of the piston rod intruding and retracting by the ring-shaped oil chamber between the inside circumference of the outer tube and the outside circumference of the inner tube. SOLUTION: In a hydraulic shock absorber 10 of a vehicle, a sliding member 20 provided on a rod guide 19 formed integrally with the inner tube 12 supports the outer tube 11 floatingly in the radial direction.
