図５（Ｂ）に示す状態にて、端子カバー１ｅはガスメータ１に取り付けられている。ここから取り付け部材１３を取り外し（取り付け時と逆方向に回して抜く）、連結部材４０ｃを取り付け時と逆方向に止まるまで回し、図５（Ｃ）の状態にする（抜け防止手段４１が挿入孔４３にあたるので抜けない）。なお、連結部材４０ｃは最初は長いネジの形状であり、端子カバー１ｅをガスメータ１に取り付けた後、裏側から抜け防止手段４１を取り付けて、図５（Ｂ）に示す構造にしている。 [Fourth embodiment (FIG. 5)]
FIG. 5 is a diagram for explaining the appearance of the connecting member 40c corresponding to the drop-off preventing means and connecting the gas meter 1 and the terminal cover 1e using the connecting member 40c in the fourth embodiment. FIG. 5A shows a perspective view of the connecting member 40c in the present embodiment. The connecting member 40c in the present embodiment is also used as one of the attachment members 13 (screws and the like) in FIGS. In the present embodiment, a screw is formed on the main shaft portion of the connecting member 40c.
In the state shown in FIG. 5B, the terminal cover 1 e is attached to the gas meter 1. The attachment member 13 is removed from here (turned in the direction opposite to that at the time of attachment), and the connecting member 40c is turned in the direction opposite to that at the time of attachment until the state shown in FIG. 43 so I can't get out). The connecting member 40c is initially in the form of a long screw, and after the terminal cover 1e is attached to the gas meter 1, the prevention means 41 is attached from the back side, and the structure shown in FIG.

このように、本実施の形態では、端子カバー１ｅの取り付け部材１３（ネジ等）と端子カバー１ｅを取り外したときの脱落を防止する連結部材４０ｃとを兼用させることができる。
なお、本実施の形態では、係合手段１６には端子カバー１ｅにおける連結部材４０ｃが挿入されている孔が相当する。
また、図５（Ａ）に示す連結部材４０ｃに対して、図５（Ｆ）に示すように主軸部（抜け防止手段４１と支持手段４２との間の部分）が、ネジが形成されているネジ部４０ｅと、ネジを形成せず且つネジ部よりも小さな径の延長部４０ｆとで構成された連結部材４０ｄを用いてもよい。連結部材４０ｄを用いた場合、図５（Ｃ）の状態にするまでにネジを回す回数が、連結部材４０ｃ用いた場合よりも低減され、作業性が向上する。 5D is a perspective view of the state of FIG. FIG. 5E shows a state in which the terminal cover 1e is rotated around the connecting member 40c from the state of FIG. 5D. In the present embodiment, a screw is also formed in the insertion hole 43.
Thus, in this Embodiment, the attachment member 13 (screw etc.) of the terminal cover 1e and the connection member 40c which prevents drop-off | omission when the terminal cover 1e is removed can be combined.
In the present embodiment, the engagement means 16 corresponds to a hole into which the connecting member 40c in the terminal cover 1e is inserted.
Further, as shown in FIG. 5F, the connecting member 40c shown in FIG. 5A is formed with a screw at the main shaft portion (the portion between the drop prevention means 41 and the support means 42). You may use the connection member 40d comprised by the thread part 40e and the extension part 40f which does not form a screw and has a diameter smaller than a screw part. When the connecting member 40d is used, the number of times that the screw is turned before the state shown in FIG. 5C is reduced is reduced as compared with the case where the connecting member 40c is used, and workability is improved.
