PROBLEM TO BE SOLVED: To prevent an arrangement box from being deformed or an electric equipment mounted inside an arrangement box from breaking, when sideway shock occurs by earthquake, by constituting a fixation member to ceiling so that the ceiling and the arrangement box may shift relatively in horizontal direction in an earthquake. SOLUTION: An arrangement box 1 is equipped with a pair of side members 6, a rear member on which to mount a breaker 2, and a cover 8, and the bottom of the side member 6 is fixed to a floor 3 through a floor fixing member 9, while the top of the side member 6 is fixed to a ceiling 4 through a ceiling fixing member 5. Here, the ceiling fixing member 5 is composed of a member fixing part 35 fixed to the side member 6, a ceiling fixing part 36 attached to the ceiling 4, and a vibration absorbing member 37 attached between the member fixing part 35 and the ceiling fixing part 36 so that the ceiling 4 and the arrangement box 1 may relatively shift in horizontal direction to the sideway shock of earthquake. Hereby, the ceiling fixing member 5 absorbs earthquake, which can prevents the arrangement box 1 from being deformed or the breaker 2 from breaking. |
