PURPOSE:To eliminate the entanglement, etc. owing to wire floating at the wire pulling by turnably disposing a guide ring support bar having a guide ring through which the wire passes on the inside surface of the containing vessel at the time of containing the welding wire in coil form in the spacing between inner and outer barrels. CONSTITUTION:A welding wire 12 is contained in coil-form in the spacing between an outer barrel 10 and an inner barrel 11. The large diameter side end of a conical support 13 is fixed to the top end of the outer barrel 10 and a wire guide pipe 14 is supported rotatably via bearing 15 to the small-diameter side end part. A guide member 16 which guides the wire 12 pulling out from the guide pipe 14 consists of the guide ring support ring 16b which has a guide ring 16a through which the wire 12 passes and the elastic floating suppressing rod 16c which is coupled at one end to the support rod 16b and contacted at the other end to the inside surface of the support 13 or the inside surface of the outer barrel 10. Namely, the member 16 is disposed turnably within the support 13 and rotates in synchronization with the wire 12 which is un-coiled so as to rotate by the un-coiling force of the wire 12 passing through the ring 16a. |
