More specifically, since the joint portion of the tubular portion is joined by welding or the like, it is generally low in strength and easily damaged. In addition, at the attachment position of the electrode part in the tubular part, the electric current density increases and the temperature tends to be high, so that it is easily damaged. Therefore, if the positions of the two are overlapped in the circumferential direction of the tubular portion, damage to the tubular portion and thus to the transfer pipe becomes significant.
