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.
