Abstract
In a fluid pressure cylinder, first and second cylinder chambers facing respective opposite end surfaces of a piston are formed inside a cylinder tube including a supply port and a discharge port, and a first piston rod connected to one end surface side of the piston is formed to have a greater diameter than that of a second piston rod connected to another end surface side of the piston. Therefore, a second pressure-receiving area of a second pressure-receiving surface formed on the other end surface of the piston is greater than a first pressure-receiving area of a first pressure-receiving surface formed on the one end surface. Pressure fluid in the first cylinder chamber is supplied to the second cylinder chamber, whereby area difference between the first pressure-receiving area and the second pressure-receiving area causes the piston to move toward the first cylinder chamber.
