PROBLEM TO BE SOLVED: To solve the problem that it is very troublesome to fit fixing metal fittings since although conventional fixing metal fittings are provided with a curved part which holds gas piping at a center part of a rectangular sheet metal, parts located on both sides of the curved part are in a flat plate shape, which only have a round hole for screwing formed, so that the fixing metal fittings swing when a first screw is completely clamped and a screw hole on the side of a fire power regulation device is not aligned with the other round hole when remaining screws are clamped.SOLUTION: Fixing metal fittings are provided with a movement prevention part which holds a stopper part formed nearby a screw hole from both sides along a length of gas piping so that when a screw is threadably engaged with one screw hole, an end of the other screw hole side is disallowed to swing.SELECTED DRAWING: Figure 5 |
