  • Patent number: 7753244
    Abstract: To upgrade the practicability of the feed of a nail connecting body in a magazine by using a spring. The magazine (4) is provided with (a) a rectilinear loading part (13) which loads the nail connecting body N; and (b) a feed member (34) which is loaded on this rectilinear loading part (13) so that it can slide easily.
