Abstract: A hydraulic shock absorber of the type having a piston fitted in a cylinder filled with a working oil to thereby construct a shock absorbing force generating mechanism, including a cylindrical shock absorbing rubber seat for preventing shock fitted onto the end portion of the piston rod; a protecting cylinder with at least its leading end having a larger diameter than that of the rubber seat fitted on the base portion of the rubber seat; a spring receiving collar fitted on the outer side of the protecting cylinder; a mounting fixture screwed onto the end portion of the piston rod, and a coil spring interposed under compression between the spring receiving collar and the cylinder so that the spring receiving collar is forced into contact with the mounting fixture. The replacement of the spring can be easily performed without damaging the rubber seat. Further, the outer circumferential side of the rubber seat is protected from being damaged by the spring when the shock absorber is compressed to its limit.
