PROBLEM TO BE SOLVED: To provide an electric oil pump device capable of preventing inflow of oil of a motor into a controller side by sealing a gap between a motor housing and a bus bar, wherein the motor has a structure in which the electric motor and the controller are integrally formed and in which the oil enters the inside.SOLUTION: A base end 19a of a cylindrical second bus bar 19 is press fitted into a first bus bar 18 fixed to an insulator 21 by integral molding, and a distal end 19b of the second bus bar 19 is connected to a substrate 24. A stator 5, a rotor holding member 22, and the second bus bar 19 are integrally molded with a motor housing 15. A circular annular seal member 27 is fitted into a plurality of annular seal grooves 26 formed between a cylindrical recess 25 of the motor housing 15 and the second bus bar 19, and seals a gap between the motor housing 15 and the second bus bar 19. Furthermore, a clearance 28 is formed between a recess 25 inner peripheral surface and an outer peripheral surface of a second bus bar connection part 18b of the first bus bar 18. |
