ABSTRACT:
A screw driving machine in which a screw having a head is screwed into a work, includes: a body; a nose section positioned toward the work with respect to the body, the nose section holding the screw to be driven; a hammering mechanism accommodated in the body, for hammering the screw into the work until the head of the screw held above the work; a screwing mechanism for screwing the screw hammered into the work; a contact arm slidable with respect to the nose section, the contact arm being pulled in toward the body when the contact arm is pushed against the work; and a locking mechanism for prohibiting the contact arm from sliding in its half way when the contact arm is pushed against the work, and for releasing the contact arm from locking after the hammering mechanism hammers the screw into the work.
