AIRTIGHT STRUCTURE OF DISTRIBUTION BOARD

PROBLEM TO BE SOLVED: To provide an airtight structure of a distribution board wherein such a situation that there is a cross beam in the wall surface to which a distributed board is attached and thereby the opening height dimension of a wiring hole must be smaller than a predetermined dimension can be coped with one type of separator. SOLUTION: A wiring hole 11 formed in the wall surface 10 is closed airtightly by means of an airtight member 13 and a separator 17. The airtight member 13 holds a wire 6 by an airtight member 14 and fixes a frame 15 to the wiring hole 11, and the separator 17 is formed substantially in the shape of a plate and fixed to close between the airtight members 13 attached above and below the wiring hole 11. The separator 17 is provided with two parallel slit grooves 17d in the horizontal direction, and when a cross beam 18 is provided in the wall 10 at the position where the airtight member 13 is attached and thereby the wiring hole 11 must be formed with a small height dimension, the height dimension is reduced by breaking the separator 17 by the slit grooves 17d and then removing the intermediate part so that the airtight member 13 and the separator 17 can be attached.
