摘要： A hydraulic shock absorber enables its piston rod to be locked near its minimum length position and allows the locked condition to be visually confirmed easily. A cap member is secured to a distal end portion of a piston rod extending from a cylinder part, and a dust cover is secured to the cap member. A lock member is secured to an end of the cylinder part from which the piston rod extends to the outside. The lock member is cut and bent upward to form engaging portions. The cap member is cut and bent downward to form engaging pieces and windows. 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.

摘要： In a cylinder apparatus in the form of a shock absorber, a spring seat is mounted within a cylinder, and clearance-fitted to a piston rod with a first lateral clearance for moving along the piston rod longitudinally of the cylinder. The spring seat includes a longitudinal extension at one longitudinal end for defining a space between the longitudinal extension and the piston rod. A rebound spring is mounted around the piston rod within the cylinder. The rebound spring has one longitudinal end fixed to another longitudinal end of the spring seat. An elastic member is retained in the defined space by the longitudinal extension of the spring seat, and clearance-fitted to the piston rod with a second lateral clearance for moving along the piston rod longitudinally of the cylinder, wherein the second lateral clearance is smaller than the first lateral clearance.

摘要： A shock absorber which facilitates an insertion/fixation operation. The shock absorber includes a spring-force application unit (84) for applying a force in a valve-closing direction to a disc valve while allowing the fixed shaft to be inserted therethrough; and a cylindrical member (47) for allowing the fixed shaft (21) to be inserted therethrough. The disc valve includes a plurality of valve discs (53) to (58). The cylindrical member is inserted into each of the valve discs (53) to (58) and the spring-force application unit (84), in which: the cylindrical member (47) is provided so as to have a radially extending gap on an inner side of the inner seat (31) of the valve main body (14).
