PROBLEM TO BE SOLVED: To provide a structure which makes it possible to cut out a hole for passing wires to a required size by a simple process in a distribution board. SOLUTION: A box body 2, to which a side panel 3 is mountable and detachable, is bent to form a rough channel shape in cross section. Furthermore, its front edge parts are bent to form bent parts 4, on which screw holes 5 are provided. The side panel 3 is bent to form a 'L' shape in cross section. Then, on the front side of the side panel 3, screw holes 7 are drilled in the box body 3 at the positions corresponding to the screw holes 5, and on the top side 9, perforations 10 are provided so that a part of it can be cut off. |
