である。FIG. 1 shows a nailing machine. This nailing machine uses compressed air as a driving source, presses a contact arm 1 against a material to be driven (not shown), and activates a trigger lever 2 for activation. The trigger valve 3 is actuated in cooperation with the pulling operation to drive the striking mechanism 5 in the body 4 to drive out the nail supplied from the magazine 6 to the nose portion 7 for nail injection.

When the base end pivots the operation piece 8 rotatably provided on the trigger lever 2 and pulls the trigger lever 2 in this state,
The operating piece 8 pushes and operates the valve stem 9 of the trigger valve 3, and the nailing machine is activated. On the other hand, even if the trigger lever 2 is pulled without pushing the contact arm 1, the nailer is not started because the operating piece 8 does not push the trigger valve stem 9.
