Abstract:
In the present invention: an air cylinder is joined to a guide pipe via a joining member; a stopper member is positioned at a location at which the guide pipe and a nut feeding pipe are linked, and a temporary stop chamber for nuts is formed; a sliding rod obtained by extension of a piston rod, and a guide rod that advances into a threaded hole and that has a smaller diameter than the sliding rod, are integrally formed; the relative positions of the temporary stop chamber and a feeding rod are set such that the feeding rod is coaxially arranged with respect to a threaded hole in a nut that has stopped in the temporary stop chamber; a vacant space is formed between the sliding rod and the guide pipe, and a support hole having a smaller diameter than the inside diameter of the guide pipe is formed in a temporary-stop-chamber-side end section of the guide pipe; and during retraction of the feeding rod, the sliding rod is supported in a state in which a very small sliding gap is reserved in the support hole.
