PROBLEM TO BE SOLVED: To solve a problem that when a feeder box is retracted with respect to a case by conventional screw fastening operation, a screw connecting band is drawn by the retraction and screws are entangled with each other, in a screw feeding device for performing pitch feeding of the screw connecting band holding a large number of screws in parallel to a screw fastening machine main body side. SOLUTION: A clearance 31e along the reciprocating direction of the feeder box 22 is provided in a fixation part 31 of a screw connecting band guide member 30, so as to separate the screw connecting band J from a guide path and move the screw connecting band J to a shortest route across the clearance 31e when the feeder box 22 is retracted. Thus, this can prevent increase in the number of screws S and the length of a sheet material T in a region between the clearance 31e and the feeder box 22. COPYRIGHT: (C)2008,JPO&INPIT
