In some cases, a plurality of piers extending along the horizontal direction and the vertical direction are provided on the wall where the gas stopper main body is installed. For such a wall part, depending on the position where the opening is formed, the pier may be located at a position where the holding part of the fixing member holds the wall part. In some cases, the part could not be clamped.
In such a case, by rotating the fixing member around the cylinder axis as viewed in the cylinder axis direction, the position where the clamping part clamps the wall part can be moved to a position where there is no pier. However, in the technique disclosed in Patent Document 1, when the fixing member is rotated around the cylinder axis, the lid mechanism needs to be rotated along with the rotation of the fixing member because of the structure. .
Thus, when the lid mechanism is rotated, the lid body that normally rotates around the pivot shaft along the vertical direction and opens and closes in the horizontal direction opens and closes in the vertical direction around the pivot shaft along the horizontal direction, for example. It becomes a state. In particular, when the lid is positioned below the fixing member in the open state, when connecting the gas connector to the connecting portion of the gas plug main body, the load of the gas cord is applied to the lid, thereby There was a risk that the lid would be damaged. For this reason, conventionally, it was impossible to rotate around the cylinder axis of the fixing member, and there was room for improvement from the viewpoint of workability.

  The present invention has been made in view of the above-described problems, and the object thereof is to install on a plurality of wall portions having different structures while maintaining the attachment direction of the lid body in a predetermined specific direction. An object of the present invention is to provide an installation structure of a gas stopper main body having a high degree of installation flexibility.

According to the above characteristic configuration, each of the pair of engaging portions is constituted by the wide first engaging portion and the narrow second engaging portion, and thus the lid mechanism is connected to the fixing member. In this case, the wide first engagement portion is engaged with the first notch portion with a relatively large engagement force, and the narrow second engagement portion is relatively small with respect to the second notch portion. Engage with the resultant force. As described above, the connection between the fixing member and the lid mechanism may be further strengthened by the engagement of the first engagement portion and the second engagement portion with the first cutout portion and the second cutout portion. it can.
However, the connection between the fixing member and the lid mechanism may need to be removed for some reason. Even in such a case, according to the above-described characteristic configuration, after releasing the engagement between the second notch portion having a relatively weak engagement force and the second engagement portion having a narrow width, the engagement force is relatively strong. The lid mechanism can be removed from the fixing member relatively easily in a form in which the engagement between the first notch portion and the wide first engagement portion is released.
