PROBLEM TO BE SOLVED: To prevent a cover from being opened mistakenly owing to a simple structure by a method, wherein a base-side coupling body and a cover-side coupling body are formed so as to be coupled to each other, when a base is covered with the cover. SOLUTION: Wiring devices 3 such as breakers and the like are mounted on a base 2 at a distribution board 1 for a house, and operating handles 4 which protrude from a cover 5 are covered with a lid body. In addition, base-side coupling bodies 7 are installed at the bottom face of the base 2, cover-side coupling bodies 8 are installed at the cover 5, tip parts of the base-side coupling bodies 7 are formed to be hook-shaped, ends, on one side of the cover-side coupling bodies 8 are bent to the nearly L-shaped, and coupling pieces 9 are constituted in such a way that the base-side coupling bodies 7 and the cover-side coupling bodies 8 are coupled to each other. Then, when the cover 5 is attached and removed, operating parts 10 at the cover-side coupling bodies 8 are moved, and the coupling pieces 9 at the cover-side coupling bodies 8 are coupled to, and removed from the base-side coupling bodies 7. As a result, when the cover 5 is opened, it is required to open the lid body. Thereby, it is possible to prevent an electric-shock accident from occurring due to opening the cover 5 mistakenly during the operation of the breakers and the like. |
