Therefore, the water droplets 8 dropped on the box 3 are blocked by the shielding plate 12 and do not enter the box 3 from the vent holes 7 of the top plate 3c. Further, since the pair of fixing plates 11 is formed in a rectangular flat plate shape and protrudes upward from the both side plates 3b of the box 3, the water droplets 8 can be prevented from flying on the top plate 3c from the side. Intrusion of the water droplet 8 into the box 3 from the vent hole 7 of the top plate 3c is suppressed. Thus, it is possible to suppress the occurrence of a ground accident and a short circuit accident caused by water droplets entering the control panel 2.

  Further, the shielding plate 12 is inclined so as to be lowered forward in the depth direction. Therefore, as indicated by an arrow in FIG. 3, the water droplet 8 can flow down to the front of the box 3 without accumulating on the shielding plate 12. Further, as indicated by an arrow in FIG. 3, air is provided in the lower portion of the front door 3a, flows from the ventilation hole 5, is warmed by the heat generated in the box 3, and is provided in the top plate 3c. Flows out of 7. The air flowing out from the vent hole 7 flows along the shielding plate 12 which is inclined without staying on the top plate 3c and is discharged. Therefore, it is possible to avoid a situation in which warmed air stays on the top plate 3c and the temperature of the box 3 rises excessively.
