An outer wall plate 2 is provided on the outer periphery of the substantially circular bowl 1, and a component conveyance path 3 is disposed along the outer wall plate 2. In the example of FIG. 1, the projection nut 4 that is a component is transferred in a counterclockwise direction through the component conveyance path 3 and sent out from the delivery pipe 5. A supply hose 6 is connected to the delivery pipe 5 so that the projection nut 4 is supplied to the target location. The parts conveyance path 3 basically has a spiral shape in which the outer peripheral side of the bowl 1 is low and gradually increases as it approaches the delivery pipe 5.

  Two guide ridges 7 are provided along the inner wall of the arc-shaped outer wall plate 2, and the part conveyance path 3 where the guide ridges 7 are arranged is such that the central portion side of the bowl 1 is lowered. It is tilted in the direction. That is, the inclination direction of the component conveying path 3 is gradually reversed in front of the guide protrusion 7. Further, from the vicinity of the end of the guide ridge 7, the inclination direction changes again in the opposite direction and returns to the original state. The portion where the inclined portion or the guide protrusion 7 is arranged is the first selection unit 8. Further, a guide plate 9 having a lower center side of the bowl 1 is formed near the center of the first sorting unit 8 in an overhanging state.

  The projection nut 4 has a square shape in which welding projections 10 are provided at four corners, and a screw hole 11 is formed at the center thereof. Ribs 12 are provided so as to connect the welding protrusions 10 in a state along the side surface of the projection nut 4. The height of the rib portion 12 is lower than the height of the welding protrusion 10. That is, the height of the welding projection 10 is lowered by the height of the rib portion 12. Therefore, the effective height at which the welding protrusion 10 is locked to the protrusion 7 is a slight height indicated by the symbol H as shown in FIGS. In other words, the height of the welding protrusion 10 is not the height from the end face of the projection nut 4 but the height from the rib portion 12.

  When the projection nut 4 having such a rib portion 12 is subjected to electric resistance welding to the steel plate component 13, the welding projections 10 and the rib portions 12 at the four corners are welded to the steel plate component 13.
