Plural bottom surface ventilation ports and plural side surface ventilation ports are provided in the motor case. Both of the ventilation ports cause air to flow into the inside of the motor case. The plural bottom surface ventilation ports and the plural side surface ventilation ports are disposed at positions lower than the air introduction member and the control device.
