The lid body is in a closed state orthogonal to the hose end from the hose end. The structure is such that it can be rotated in an open upright posture that is upright parallel to the end, and that in this open upright posture it can move forward and backward in the direction perpendicular to the decorative plate.

The socket is detachable from the hose end when the lid body in the open upright posture is pushed in while the socket connected to the gas rubber tube on the instrument side is connected to the hose end. Therefore, there is an advantage that the number of operating portions of the decorative plate is smaller than that in the case where the mechanism for removing the socket is provided separately from the lid for opening and closing the gas pipe connection port.

However, in the conventional wall-embedded gas plug of this type, since the decorative plate having the socket removing mechanism and the operating portion is directly attached to the gas plug main body, the gas inside the wall is closed. When the distance from the fixing position of the stopper body to the interior wall surface does not match the height of the skirt portion of the decorative plate, a gap is generated between the decorative plate and the indoor wall surface, and it is inevitable that the appearance is unsightly.

In order to solve this problem, a method may be considered in which a cover is provided on a decorative plate and this decorative plate is screwed to the gas stopper main body side. If the distance from the decorative plate is different, the interlocking relationship with the socket removal mechanism provided on the gas stopper body side is deviated, and it becomes difficult to realize a smooth removal operation under each condition.

The present invention has been made in view of the above-mentioned point, and "A gas pipe connection port of a decorative plate for accommodating and fixing a gas plug main body inside a wall and fixed to an inner wall surface of this wall in an attached state.
