摘要： PROBLEM TO BE SOLVED: To provide a pneumatic driving machine improved in durability.
SOLUTION: A nailing machine 1 includes an air passage 510 allowing communication between a cylinder 200 and a return air chamber 500 for accumulating compressed air for returning a piston 300 to an initial position. The air passage 510 is provided with: a control valve 520 controlling inflow of the compressed air into the return air chamber 500 from the cylinder 200. The control valve 520 opens the air passage 510 and allows the inflow of the compressed air into the return air chamber 500 when the reaction force from a driven material in driving of a nail is small, in other words, when the upward moving distance of a body 100 relative to a push lever 700 is smaller than a predetermined distance. The compressed air flowing in the return air chamber 500 flows in a piston lower chamber and serves as an air damper, thereby reducing excess energy absorbed by a piston bumper 360.
