PURPOSE:To simplify the connecting and disconnecting between a pilot burner part and a nozzle by a method wherein a gas conduit of which end part is formed as the nozzle is fixed by pressing with a spring member. CONSTITUTION:A bent piece 5b disposed in upright position on a base member 5 is provided with a circular hole having a slightly larger diameter than the external diameter of a pipe nozzle at the position being coincided with the central axis of a curl-shaped part 5c. After the end of a pipe nozzle 6 is passed through the circular hole of the bent piece 5b, the pipe nozzle 6 is arranged on a bent piece 5a having a U-shaped groove. At the arrangement of the pipe nozzle 6, a collar part 6a which is formed by expanding a part of the pipe nozzle 6 is arranged at the related position where the collar part is contacted with the side wall at a curl-shaped side or the side wall at an opposite side of the bent piece 5a. Thereby, the pipe nozzle 6 is fixed without moving forward or backward. After the pipe nozzle 6 is arranged on each bent piece 5a, 5b, both ends of a wire pin 7 is inserted through wire pin fixing grooves 5g, 5h which are provided on the base member 5 for preventing of upward moving of the pipe nozzle, thus the pipe nozzle 6 is fixed by pressing from above thereof with the wire pin 7. |
