<P>PROBLEM TO BE SOLVED: To provide an electric oil pump device capable of being operated stably by suppressing adverse effect caused by noise to the inside/outside of motor control circuitry. <P>SOLUTION: A pump housing 15, a fixing member 8 and a holding member 17 are combined to each other to fix a stator 5 and a rotor 6 of a brushless motor 3. In the metallic holding member 17 of which the one side is cylindrical, the outer edge thereof is fitted into the outer edge of a ring 8, and fastening parts 18a, 18b for fixing a substrate 19 are formed along the outer circumference of the opposite-side end face and abutted to a ground part of control circuitry 20 provided on the substrate 19, thereby forming an electrical ground passage connected from the ground part of the substrate 19 to the pump housing 15. A bushing 25 is fitted into a through-hole 28 formed in a flange part 23 protruding on the end face of the pump housing 15. A bolt 24 is screwed to a vehicle case 22 through the bushing 25 and the flange part 23 is supported in an insulative manner while having a gap with respect to the vehicle case 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
