Abstract: A fluid pressure cylinder driving device includes a switch valve, a high pressure air supply source, an exhaust port and a check valve. When the switch valve is at a first position, a head side cylinder chamber communicates with the high pressure air supply source, and a rod side cylinder chamber communicates with the exhaust port. When the switch valve is at a second position, the head side cylinder chamber communicates with the rod side cylinder chamber via the check valve, and the head side cylinder chamber communicates with the exhaust port.

Abstract: A cylinder main body of a fluid pressure cylinder includes a switch valve, a check valve, and a flow path communicating a high pressure air supply source with a head side cylinder chamber and communicating an exhaust port with a rod side cylinder chamber when the switch valve is at a second position. Another flow path communicates the head side cylinder chamber with the rod side cylinder chamber and the exhaust port when the switch valve is at the first position.
