PROBLEM TO BE SOLVED: To provide a nailing machine precisely aligning an injecting groove formed on a bit guide and an injecting groove formed on a contact arm in driving a headless nail. SOLUTION: This box nailing machine is devised so that: the flat bit guide 12 has a roughly V shape, a rod part is branched and extended from the head end of the bit guide 12 to both the right and left sides thereof, and the bit guide 5 is connected to a connecting arm on one side of the rod part; torque 66 works on the contact arm 5 by energizing force generated in the injecting direction on the one side of the rod part in pressing the contact arm 5 on a driven material; and in only either one of clearances in the right and directions between the bit guide 12 and the contact arm 5, the bit guide 12 and the contact arm 5 are abutted by the torque 66 to align the fixed injecting groove 36 and the movable injecting groove 37 when abutted.
