ABSTRACT:
A nail feeding mechanism is provided with a front feed claw (9) and a rear feed claw (10). The rear feed claw (10) is provided with a contact portion (10b) on a front side of a claw portion (10a). A face of the contact portion (10b) to be brought into contact with connected nails is wider than a gap between nails in a width thereof and cannot enter between nails. When the front feed claw (9) is moved rearward and catches a final nail (TN1) of a first row, the contact portion (10b) and the claw portion (10a) move into a nail path, the contact portion (10b) enters between the final nail (TN1) of the first row and a front nail (FN2) of a second row and the claw portion (10a) enters a rear side of the front nail (FN2) of the second row. After feeding nails, the feed claw is moved rearward, the contact portion (10b) and the claw portion (10a) ride over side faces of the second row of connected nails (N2) to return to escaping positions and the feed claw (9) is engaged with the front nail (FN2) of the second row to continue nail feeding.
