Abstract
A projection portion is formed on a distal end surface of a supply rod with which a surface of a flange is to be brought into close contact. A circular-arc receiving surface fitting an outer peripheral portion is formed at a boundary portion between the distal end surface and the projection portion. One side of the circular-arc receiving surface is continuous with the distal end surface, and another side of the circular-arc receiving surface is continuous with a regulation inner surface formed on the projection portion in a state of being opposed to the distal end surface. With this, a receiving groove is formed, and a control gap is defined between the regulation inner surface and the flange. The close contact of the surface with the distal end surface is achieved with a magnet of an advancing/retreating type provided in the supply rod.
