To provide a device for supplying a component to an electrode receiving hole that accurately inserts a shaft-like component into an electrode receiving hole by a simplified structure.

A shaft-like component is composed of a shaft, a circular flange, and a welding protrusion. A receiving hole is opened on the end face of an electrode 5 so as to allow the shaft to be inserted into the receiving hole. A tapered hole 24 is formed in a guide member 23, advancing to and retreating from an advancing an retreating space of the electrode 5, so as to guide the shaft to the receiving hole. The guide member 23 is formed in an opening and closing structure divided into two parts of a one-side guide member 27 and the other-side guide member 28. When the one-side guide member 27 and the other-side guide member 28, having advanced to a predetermined position, are closed, the tapered hole 24 and the receiving hole are put into a coaxial state. Thus, the shaft is surely inserted into the receiving hole.
