To provide a weld nut feeding device capable of certainly feeding the weld nut to a welding position without bending a feeding rod.

In the weld nut feeding device, the weld nut 20 fed from a nut feeder is received by a receiving part of a nut receiver, the feeding rod 4 expanded/contracted in an axial direction is pierced to a screw hole of the weld nut 20 in the state, and the weld nut 20 is fed to the welding position. A bottom part of the receiving part of the nut receiver 5 is made to a recession arc surface of a semi-circular cross section shape. Further, the nut receiver 5 is preferably detachably constituted, and a level difference part 4b having a diameter larger than an outer diameter of the feeding rod 4 and inserted to the screw hole of the weld nut 20 is preferably formed on a base end of the feeding rod.
