Fluid pressure cylinder
In a fluid pressure cylinder, a piston is displaced in an axial direction under the action of a pressure fluid. A circular protrusion, which projects toward the piston along an axial direction of the cylinder tube, is formed on an inner end surface of a collar member constituting part of the fluid pressure cylinder, a concavity, which can be fitted externally over the circular protrusion, is formed on the piston, and an annular groove is formed on an inner circumferential edge of an end plate. By the piston coming into contact with the end plate, a pressure receiving chamber is formed between the piston and the annular groove, together with an opening of a second port on an inner side of the cylinder tube being closed to a maximum of 90%.
