In a vehicle in which side covers are disposed at the underfloor sides of a vehicle body, a totally enclosed main motor is disposed outside a frame of a chassis. The totally enclosed main motor includes an outside air ventilating flue through which the outside air is suctioned from a suction inlet, circulated and then exhausted from an exhaust outlet. The totally enclosed main motor uses the outside air ventilating flue to release heat generated internally to the outside. One end of a ventilating duct is connected to the suction inlet and the other end opens toward the outside of the vehicle at the side covers. With this, it is possible to supply the outside air from the outside of the vehicle thereby enhancing the cooling efficiency. Moreover, it is possible to use the totally enclosed main motor of a high capacity by disposing outside the frame of the chassis. |
