PROBLEM TO BE SOLVED: To provide a nailing machine in which compressed air is fed into a cylinder so as to carry out nailing when a nailing machine body is pressed so as to raise a piston by a predetermined degree, and which can prevent nailing operation from being performed, unless a drive guide is moved upward so as to manipulate a trigger in order to prevent erroneous operation for a substandard nail. SOLUTION: In a nailing machine, an auxiliary air chamber AA is provided between a cylinder 13 and an accumulator chamber A, and a trigger valve 93 is located between the auxiliary air chamber AA and an accumulator chamber A. Compressed air is fed into the auxiliary air chamber AA from the accumulator chamber A only when the trigger valve 93 is turned on by pulling a trigger 92, and accordingly, the nailing operation is carried out through the pushing operation of the nailing machine body.
