A ventilation opening 71 is opened on the side wall of the DC side chassis 7 perpendicular to the partition part 2 , and the cooling fan 16 is arranged at the ventilation opening 71 . Therefore, in the DC side box 7, the inverter unit 1 is arranged at the upper part, the DC power distribution unit 8 is arranged at the front of the lower part, and the cooling fan 1 16, the air duct 18 and the DC filtering device 19 are arranged at the rear.
