Abstract
A fluid-pressure shock absorber comprising: an external cylinder with an open portion provided at one end thereof, a piston rod, a tip of which projects from the open portion of the external cylinder; a rod guide, wherein the open portion of the external cylinder is closed with caulking works so as to make a caulking portion, and further comprising: an annular bump cap coaxially arranged relative to the external cylinder; a cap holder arranged on a side of the tip of the piston rod relative to the rod guide so as to retain the bump cap, wherein an end portion on the rod guide side of the bump cap is abutted to the caulking portion, and a clearance in an axial direction is formed between an end portion of the cap holder on a side towards the tip of the piston rod and the bump cap.
