Since the outdoor condenser is disposed in a horizontal state with the cooling core surface disposed on the upper surface, and the outdoor condenser is disposed inclined, the installation height of the outdoor condenser and the condenser cover covering the outdoor condenser can be suppressed. In addition, it is possible to prevent the field of view from the inside of the cabin from being obstructed by the outdoor condenser, thereby maintaining a good field of view and securing a wide viewing range. In addition, by arranging the outdoor condenser with the cooling core surface on the upper surface and sloping to the front low and rear high, the cooling air flowing from the front to the rear can easily contact the cooling core surface, reducing the cooling effect. It is possible to efficiently cool the outdoor condenser by increasing the temperature.

The cooling air is taken into the inside from the air intake and exhaust holes formed on the front and upper surfaces of the capacitor cover to cool the outdoor condenser, and the cooling air after cooling the outdoor condenser is formed on the rear and outer surfaces of the condenser cover. The air can be discharged from the pores to the outside, and the outdoor condenser can be sufficiently cooled. Further, since the intake and exhaust holes on the upper surface of the capacitor cover are formed so as to be shifted from the arrangement position of the electrical components in the capacitor cover, even when water enters the interior through the intake and exhaust holes formed on the upper surface of the capacitor cover during rainfall or the like. In addition, it is possible to prevent the electric components such as the drive motor housed in the capacitor cover from hitting the electric components, thereby preventing the electric components from breaking down.
