PROBLEM TO BE SOLVED: To improve the stability and mounting strength of a gas cock mounting state by changing the shape of a rear frame according to the construction condition of a wall plate while maintaining strength, in a gas cock mounting metal fitting composed of a front frame and the rear frame which pinch the periphery of an opening formed in the wall plate from two sides.SOLUTION: The rear frame is composed of an attachment frame 21 corresponding to the opening and an adjustment plate 22 extending in an orthogonal direction from one side 21a of the attachment plate. First and second cut sides 35a, 35b are formed along base end sides of first and second projecting pieces 3a, 3b extending in the vertical direction of the adjustment plate 22. A third cut side 36 is formed in a predetermined position along the base end side of the adjustment plate 22. Only after the first and second projecting pieces 3a, 3b are cut out at the first and second cut sides 35a, 35b, cutting at the third cut side 36 is performed. |
