<p>A hydraulic shock absorber (1) enables its piston rod (3) to be locked near its minimum length position and allows the locked condition to be visually confirmed easily. A cap member (7) is secured to a distal end portion of a piston rod (3) extending from a cylinder part, and a dust cover (8) is secured to the cap member. A lock member (12) is secured to an end of the cylinder part (2) from which the piston rod extends to the outside. The lock member is cut and bent upward to form engaging portions (13). The cap member is cut and bent downward to form engaging pieces (14) and windows (15). With the piston rod contracted to near its minimum length position, the cap member is rotated to engage the engaging portions and the engaging pieces with each other, thereby locking the piston rod. The engaged condition of the engaging portions and the engaging pieces can be visually confirmed through the windows.</p> |
