Abstract:
An EPU (50) has a motor unit (100), a blower device (120), and a labyrinth structure part (700). The motor unit (100) has a motor (61), an inverter (81), and a unit housing (101). The unit housing (101) accommodates the motor (61) and the inverter (81) in a unit space (102). In the unit housing (101), a unit inlet (112) and a unit outlet (114) are in communication with the unit space (102). In the EPU (50), blowing by the blower device (120) causes cooling air to flow into the unit space (102) from the unit inlet (112) and to flow out from the unit outlet (114). The cooling air flows into the unit inlet (112) after passing through the labyrinth structure part (700). In the labyrinth structure part (700), foreign matter is removed from the cooling air.
