An object of the present invention is to ensure that, during adjustment of a spring load by an adjuster, total fully-stretched lengths of an outer tube and an inner tube remain unchanged and the adjuster is prevented from protruding from an upper surface of a cap. In a hydraulic shock absorber 10, a spring load adjusting device 30 is configured such that an adjuster 31 is provided at an upper end portion of a vehicle body side tube 11, a push rod 33 that is moved up and down by the adjuster 31 is penetrated into a hollow portion of a hollow rod 23, a suspension spring 35 is pressurized by the push rod 33 that protrudes from the hollow portion of the hollow rod 23 to the inside of a wheel side tube 12, and the spring load of the suspension spring 35 can be adjusted by the up-and-down motion of the push rod 33 caused by the adjuster 31.
