The lever 13 includes a bifurcated portion 13a, the plug portion 12 is sandwiched between the bifurcated portion 13a, and the bifurcated portion 13a swings in the depth direction corresponding to the thickness direction of the wall material W. It is attached to the gas plug main body 11 in a free state. Here, in the depth direction, the direction on the front surface side of the wall material W is referred to as the near side, and the direction on the back surface side of the wall material W is referred to as the back side.
The release lever 13 is biased back in a direction in which the bifurcated portion 13a swings in the depth direction, and as the bifurcated portion 13a swings in the depth direction, the lever 13 The bifurcated portion 13a is configured to come into contact with the advancing / retracting cylinder 4 of the gas socket S attached to the gas stopper main body 11 so that the advancing / retracting cylinder 4 can be retracted.

Next, a configuration for attaching the gas outlet C to the back surface of the wall material W will be described.
As shown in FIG. 11, the gas outlet C is attached to the back surface of the wall material W using the attachment member F. The attachment member F includes a rectangular frame-shaped front frame 14 attached to the surface side of the wall material W along the opening edge of the opening Wa formed in the wall material W, and a wall along the opening edge of the opening Wa. A rectangular frame-shaped back side frame 15 attached to the back side of the material W, a mounting base 16 attached to the back side of the back side frame 15 with a gap, and the like are provided.

The front side frame body 14 and the back side frame body 15 are attached to the front and back sides of the wall material W by being connected by a plurality of screws 17 with the wall material W interposed therebetween.

Furthermore, as shown in FIG.1 and FIG.11, the front cover 20 which covers the opening part Wa of the wall material W is comprised so that it can attach to the front side frame 14 so that attachment or detachment is possible.
A rectangular recess 20a is formed on the surface of the front cover 20, and a circular shape for allowing the tip of the plug portion 12 of the gas outlet C attached to the attachment member F to face the bottom of the recess 20a. An opening 20b for plug exposure and an elongated rectangular door body insertion hole 20c located on the side of the opening 20b for plug exposure are opened.
In the front cover 20, the door body 21 is fitted into the recess 20a in a posture in which the surface direction is orthogonal to the depth direction, and the plug exposure opening 20b is closed (not shown), and the surface direction is the depth. Can be switched to a standing posture (see FIG. 1) that opens the plug exposing opening 20b in a state of being inserted into the door body insertion hole 20c in a posture along the direction, and is reciprocated in the depth direction in the standing posture. It is provided freely.
Then, when the door body 21 in the standing position is pushed into the depth side, the lever 13 is swingable in a direction in which the forked portion 13a moves to the near side in the depth direction.

It depends on the size. That is, the thicker the wall material W is, the more the plug portion 12 is located on the far side from the surface of the wall material W.
When the socket body 1 is inserted into the gas plug body 11 with the plug portion 12 inserted into the tip opening 1a, the amount of protrusion from the surface of the wall material W in the socket body 1 is the amount of the wall material W. The smaller the thickness, the smaller.
Therefore, when the size of the socket main body 1 in the front-rear direction of the socket is shortened to reduce the size of the gas socket S, the surface of the wall material W in the socket main body 1 in the state where the gas socket S is attached to the gas outlet C is used. Since the protruding amount of the gas socket S becomes small, the attaching and detaching operation of the gas socket S is performed in which the rear end portion of the socket body 1 is grasped with a finger and the gas socket S is attached to or detached from the gas outlet C. It becomes difficult.
