Abstract: A fluid pressure shock absorber includes a piston connected to an end of a piston rod and slidably moving inside a cylinder tube and dividing the cylinder tube into a piston-side chamber and a rod-side chamber, a rod internal space formed inside the piston rod, a first communication passage communicating the rod-side chamber with the rod internal space, a second communication passage formed in the piston and communicating the piston-side chamber with the rod internal space, and a restrictor provided in the second communication passage to apply a resistance to a flow of a working fluid passing through the second communication passage.

Abstract: A cylinder device includes an annular cushion ring that prevents collision between the cylinder head and the rod head at stroke end during contraction. The cushion ring is formed by linking a plurality of ring segments in a circumferential direction so as to have an annular shape. The ring segments have a main body portion and linkage portions formed on both ends of the main body portion in the circumferential direction, the linkage portions linking the neighboring ring segments. The linkage portions of the neighboring ring segments are mutually overlapped in an axial direction of the cushion ring and linked such that relative movement in a radial direction of the cushion ring is restricted.

Abstract: A cylinder device includes a piston rod that is inserted into a cylinder so as to be movable back and forth. The piston rod has a rod portion that extends outside the cylinder, and a piston connected to an end portion of the rod portion, the piston moving in the cylinder in a slidable manner. The rod portion has a rod inner space formed in the rod portion, the rod inner space communicating with the piston-side chamber of the cylinder, a first communicating passage that connects the rod inner space and the rod-side chamber of the cylinder, and an orifice plug provided in the first communicating passage in a changeable manner. The piston is connected to the rod portion so as to cover a part of the orifice plug.
