Title: Nut feeder for feeding nuts for resistance welding

Abstract: The present invention discloses a nut feeder for the feeding of nuts for resistance welding. A stopper 12 is provided which is so energized as to enter into the inside of a chute 7 from a lower-end lateral side of the chute 7. A lowermost nut 5 in the chute 7 is held by the stopper 12, thereby being prevented from falling. With a pin 11 of the nut receiver 9 set against a projection part 29 of the stopper 12, a nut receiver 9 is moved backward together with the stopper 12, by which the holding of the nut 5 is released. Then the nut 5 is placed at a position ahead of the pin 11 of the nut receiver 9 while leaning against the stopper 12. Thereafter the nut receiver 9 is moved forward and the nut 5 falls down so that its threaded hole fits onto the pin 11 and is delivered to under the upper electrode.
