In an air cylinder in which supply and exhaust ports are provided in each of the head cover and rod cover at both ends of the cylinder body, one of the above-mentioned force bars has a control import, and the other A control out port connected to the supply/exhaust port of the cover is provided, and a control valve is built in to open and close the passage connecting these inlets and outports.Furthermore, one cover is provided with a control valve that opens and closes a passage connecting these inlets and outports. A plunger that partially protrudes into the main body is slidably built in, and by pushing this plunger against the spring, the control valve can be opened. Air can be sent into the cylinder body through the supply/exhaust port of the cover, and on the other hand, a plunger pushing body for pushing the plunger is attached to the piston or piston rod, and the plunger is slidably attached to the piston or the piston rod by a spring. The control valve is opened by sliding the piston rod and piston toward one cover side using an external force until the plunger pushing body collides with the plunger and pushes it. Air can be introduced into the cylinder body from the other cover side and act on the piston, and this action causes the piston to be pushed by the spring of the plunger pushing body while the plunger is still pushing the plunger as described above. 1. An air cylinder characterized in that it can be automatically slid toward one cover side against resistance, thereby also allowing a control valve to be held open. 2. The air cylinder according to claim 1, wherein a control import, a control out port, a control valve, and a plunger are provided on a rod cover, and a plunger pushing body is slidably mounted on the outer periphery of a piston rod. 3. The air cylinder according to claim 2, wherein the plunger pushing body is biased toward the plunger by a spring disposed between the plunger pushing body and the piston.
