Claims

[Scope of Claim for Utility Model Registration] A device for attaching a gas stick to a through hole formed in a wall, comprising: a front flange disposed on the surface side of the wall around the periphery of the through hole; and a back surface of the wall around the periphery of the through hole. It consists of a back flange placed on the side, and a tightening screw inserted into the through hole to connect the two flanges.By tightening the tightening screw and sandwiching the wall between the front flange and the back flange, the front flange A gas tank mounting device for fixing a gas tank connected to a wall to a wall, characterized by having the following configurations (a) to (d). (a) The back side flange has a backing ring formed with an external dimension that allows it to pass through the through hole with the tightening screw screwed into its own screw hole, and the backing ring and the back surface of the wall. It is composed of a plurality of collar pieces held in between. (b) The collar piece is attached to the front surface of the backing ring in parallel with the backing ring, and is capable of sliding inward and outward in the radial direction of the backing ring. (c) The above-mentioned collar piece can pass through the through hole in the wall when it is in the radially inner position, and its outer periphery is located outward from the inner periphery of the through hole in the wall when it is in the same outer position. It is formed in size. (d) The collar piece is biased outward in the radial direction of the backing ring by a spring member.
