PROBLEM TO BE SOLVED: To provide a motor for an oil pump which prevents the deterioration of the sealability with a simple structure.SOLUTION: A motor 1 for an oil pump connects with an oil pump 81 through a connection hole 85 of a housing 82 so as to drive the oil pump 81 for pressurizing a differential oil N accumulated in a differential device 80. The motor 1 for the oil pump comprises: a yoke 2 having a cylindrical part 2b; a bracket 17 covering the one end side of the yoke 2; and a rotation shaft 5 rotatably supported in the yoke 2. The bracket 17 comprises: a fitting part 25 which is provided at a position separated from the rotation shaft 5 to the radial outward side and is formed so as to fit in the connection hole 85; and an inner flange part 26 formed at the differential device 80 side of the fitting part 25 and extending from the fitting part 25 to the radial inward side. A fine space S1 is formed between the inner flange part 26 and the rotation shaft 5. |
