A motor, an inverter substrate electrically connected to the motor, a housing accommodating the motor and the inverter substrate, and a pump section driven by the motor are included. The inverter substrate is disposed on one side of the motor. The pump section is disposed on the other side of the motor. The housing has a motor housing section accommodating the motor, an inverter housing section accommodating the inverter substrate, and a breather section establishing communication between inside and outside of the housing. The motor housing section has an accommodation tubular section accommodating the motor and a brim section spreading outward in a radial direction from an end of the accommodation tubular section. The inverter housing section is disposed on one side of the brim section and overlaps the brim section when seen in the axial direction. The breather section is disposed at the brim section.

Electric pump device

A point at which an external power supply is installed is registered in map data in a map information device as a base point. An EV running area centered on the aforesaid base point is registered as map data in the aforesaid map information device. When running towards the base point from outside the EV running area, while performing HEV running before arriving in the EV running area, the charge value of the battery is increased beforehand. Hence, when the vehicle enters the EV running area, it switches to EV running.

Hybrid vehicle

A point at which an external power supply is installed is registered in map data in a map information device as a base point. An EV running area centered on the base point is registered as map data in the map information device, and EV running is performed when a vehicle is in the EV running area.
