Claims

[Scope of utility model registration request]

A main cylinder is provided with a main piston that is installed in the housing of the nailer body and is moved forward and backward in the axial direction by air pressure for nail driving operation. a first side valve fitted so as to be movable in the axial direction near the base end of the main cylinder in order to communicate or cut off communication between the first cylinder chamber and the compressed air supply chamber; near the tip of the main cylinder in order to open and close the exhaust port provided near the tip of the main cylinder to communicate with or block off the exhaust port from a second cylinder chamber defined on the tip side of the main cylinder. A nailing machine characterized in that a second side lub fitted so as to be movable in the axial direction is attached so that the synchronous movement in opposite directions can be controlled by air pressure.
