PROBLEM TO BE SOLVED: To enhance efficiency in manufacturing and wiring by a structure wherein a housing is formed by riveting a metal plate, a wire lead-in plane is split vertically into a lower part being secured as a part of housing and an upper part being bent to form a wire lead-in part and the wire lead-in part is provided with a notched part and a protective wall surrounding the notched part. SOLUTION: A housing 1 is hinged to a door 2 and fixing seats 4 are bonded to the lower surface of the housing 1 at four corners thereof. The housing 1 comprises first through third side plates 11-13, and a fourth side plate 14 forming a wire lead-in part and riveted, at four corners thereof, through corner members 16. Each side plate 11-13 and the fourth side plate 14 are bend inward on the lower side thereof and a bottom plate 17 is riveted 10 thereto. The fourth side plate 14 is split vertically into two and the lower body 14 of wire lead-in part is bent outward by 90 deg., at the upper end thereof, to form a wire receiving part 14a while the upper body 15 of wire lead-in part is provided with a central protective cover 15a and the plate body is cut off on the inside thus forming a wire lead-in port 15b. Furthermore, it is secured, at the opposite ends thereof, to corner members 16 by means of screws 5. This structure facilitates manufacturing and wiring while reducing the cost. |
