An opening is formed in the inner ceiling plate, a support plate is provided on the peripheral portion of the opening on the upper surface of the inner ceiling plate via packing, and a plurality of electronic cooling devices are provided on the support plate, in front of the radiation fins of the cooling device and Since the intake port and the exhaust port are formed in the rear and the cooling fins are inserted into the main body through the openings of the ceiling plate, the cooling fins absorb the heat of the upper part of the main body, and the heat absorption amount is radiated by the heat radiation fins. The radiated air is forcibly convected from the intake port to the exhaust port, the upper portion of the main body is cooled, the inside of the main body is uniformly cooled, and the air inside the main body is efficiently cooled. Moreover, the radiating fins do not project to the outside of the main body, which improves the appearance.

Further, a rain shield is provided on each of the outside of the intake port and the exhaust port of the electronic cooling device, and a plurality of drain holes are formed on the support plate below the rain shield and outside the packing. The water receiver provided between the inner ceiling plate and the side plate is formed below the bent piece of the inner ceiling plate and forms a receiving portion that is inclined rearward, and is located inside the bent piece. The inner edge part was formed by bending upward from the inner edge of the receiving part, and the outer edge part that overlaps the upper part of the outer surface of the side plate on both side surfaces of the upper frame was formed by bending down from the outer edge of the receiving part. Rainwater invading from the outside hits the rain shield, flows from the drain hole to the receiving part of the water receiver through the bent piece of the inner ceiling plate, and the rainwater of the receiving part is prevented from flowing inward by the inner edge part, While flowing backward from the receiving part, it also flows from the receiving part to the side plate through the outer edge part, preventing rainwater from entering the main body. .
