Original Abstract Submitted
An EPU includes a motor unit, a blower device, and a labyrinth structure portion. The motor unit includes a motor, an inverter, and a unit housing. The unit housing accommodates the motor and the inverter in a unit space. In the unit housing, a unit inlet port and a unit outlet port are in communication with the unit space. In the EPU, as the blower device blows air, cooling air flows into the unit space from the unit inlet port and flows out from the unit outlet port. The cooling air flows into the unit inlet port after passing through the labyrinth structure portion. In the labyrinth structure portion, foreign matter is removed from the cooling air.
