PROBLEM TO BE SOLVED: To provide a driving machine, driving a staple each time vertically into a material to be driven to achieve good finish. SOLUTION: This pneumatic tacker nailing machine (the driving machine 1) includes: a body 2 including a driver blade for striking a staple, an injection part 26 for projecting the staple struck by the driver plate, and a trigger for controlling the driving operation; and a push lever 27 slidably supported on the body 2 and energized in the stable projecting direction by a spring (an energizing means), wherein the driving operation is performed by cooperation of the drawing operation of the trigger and the pressing operation of the push lever 27 against the material to be driven. In a front view, the angleθmade between the sliding shaft center of the push lever 27 and the contact surface with the material to be driven of the push lever 27 is set toθ>90°.
