9 are attached. A rubber packing 10 is mounted between the support members 9 and 9 and the inner surfaces 7a and 8a of the side plates 7 and 8. The upper housing 5 is fixed to the lower housing 1 by being screwed to the upper end 11 a of the mounting plate 11 erected on the bottom plate 2 of the lower housing 1 from the upper plate 6 side with screws 12. In addition, the height of the mounting plate 11
The size of the packing 10 is set in advance so as to be strongly sandwiched between the support member 9 and the upper ends 3 b and 4 b of the side plates 3 and 4 of the lower housing 1. For this reason, the infiltration of moisture into the interior from the mating portions of the housings is prevented by the packing 10.
