As shown in FIG. 8, the base 13 is formed by welding four base frames 18 combined in a frame shape. In the present embodiment, a base frame arranged on the front side and the rear side in particular will be described as a front and rear base frame 18a, and a base frame arranged on the left and right side surfaces will be described as a left and right base frame 18b. The base frame 18 has a frame shape and is substantially U-shaped in cross section with an opening 19. As shown in FIG. 1, the housing body 1 is fixed to the upper surface, and the lower surface is the installation location. It becomes a fixed surface to be fixed to. On the upper surface of the base frame 18, water drops that reach the base 13 through the drainer 8 are drained from the base 13 at positions corresponding to the lower side of the drainer 8 formed in the vertical frame 2. A drain outlet 20 is provided. As shown in FIG. 9, the drainage port 20 is provided across the connected vertical frames. As a result, water droplets that have traveled through the draining portion 8 of the vertical frame 2 are drained from the base 13 via the drain port 20, so that no water drops accumulate on the base 13. Further, the water droplets drained from the drain port 20 are guided into the base frame 18. In addition, the inside of the base frame 18 means the inside of the opening part 19 surrounded by the upper surface to which the housing body 1 of the base frame 18 is fixed, and the lower surface fixed to the installation location. Further, by providing the drain port 20 below the draining portion 8 formed in the vertical frame 2, it is possible to avoid the problem of water droplets entering the housing body 1 from the gap between the lower end of the vertical frame 2 and the base 13. It becomes.

  Specifically, the housing body 1 of the present embodiment is configured such that the bottom of the vertical frame 2 is covered by the bottom plate 12 as shown in FIGS. 6, 7, and 12.
