A mounting plate portion 81c attached to the stud 91 (support material) on the back side of the wall plate 90 and a mounting plate portion 81c extending outward from the wall plate 90 from the inner periphery of the window hole 81a of the frame plate portion 81b move the holder 83 in the inner and outer directions of the wall plate 90. It has a support plate portion 81d that can support the device.

In order to attach the gas stopper 80a to the wall board 90 using the gas stopper mounting device 80, first, before installing the wall board 90, attach the mounting plate portion 81c of the bracket 81 to the stud 91 on the back side of the wall board 90. Next, the gas stopper 80a is attached to the holder 83 via a fixture 80b (FIG. 22) provided on the gas stopper 80a, and the support plate portion 81d of the bracket 81 supports the holder 83 so as to be movable in the indoor and outdoor directions. Thereafter, by moving the holder 83 to a position in the outdoor direction, the gas plug 80a is placed in a temporarily attached state.

Subsequently, the wall plate 90 is constructed, and the wall plate 90 is cut out from inside the room along the window hole 81a of the frame plate portion 81b of the bracket 81 to form a through hole 90a. By moving the holder 83 toward the room from this through hole 90a along the support plate portion 81d of the bracket 81, the gas plug 80a is drawn to a predetermined position.

After the operation unit 84 is accommodated in the through hole 90a so as to surround the plug portion of the gas valve 80a, the fixing frame 82 is attached to the front side of the wall plate 90 and the position is adjusted. Mounting screws 85 are inserted into two insertion holes diagonally outside the window hole 82a of the fixed frame 82, and the operating unit 84 is inserted therethrough and screwed into the fixture 80b (FIG. 22). As a result, the fixed frame 82 and the holder 83 are connected and fixed.

Further, the mounting screws 86 are inserted into two elongated holes located above and below the window hole 82a of the fixed frame 82, and are screwed into the frame plate portion 81b of the bracket 81. As a result, the fixed frame 82 and the bracket 81 are connected and fixed, and the fixed frame 82 is pressed against the wall board 90. In this way, the gas plug 80a is attached to the wall plate 90. Thereafter, a plate frame 87 is attached so as to surround the fixed frame 82, and a decorative plate 88 is attached so as to overlap the plate frame 87, thereby completing the installation of the gas plug.
