。 A double-acting, single-rod cylinder in which a piston rod extending in one axial direction from a piston in a cylinder tube projects outward through a head cover at one end of the cylinder tube, and a double acting piston rod extending from a piston in a cylinder tube in one direction in the axial direction projects outward through a head cover at one end of the cylinder tube. A pipe connector is provided, and a first port that communicates one of the two pipe lines of the double pipe connected to the connector with the first pressure chamber between the end cover and the piston, and a first port that communicates the other pipe line with the first pressure chamber between the end cover and the piston. a second port connected to a fluid passage leading to a second pressure chamber between the piston and the head cover, the connector being provided on the outer end surface of the end cover;
A double acting device characterized in that each connection port of the connector connected to each pipe line of the heavy pipe is opened in the cylinder axial direction, and each port is formed to extend straight from each connection port in the cylinder axial direction. Single rod cylinder.
