<p>PROBLEM TO BE SOLVED: To provide an electric motor capable of preventing generation of assembly failures and preventing reduction in quality.SOLUTION: A electric motor comprises a motor case, and a gear case 10 for fixing this motor case. This gear case 10 is provided with: a reference positioning convex part 21 restricting movement toward at least one arbitrary direction of radial directions of the motor case, and deciding an attachment position of the motor case to the gear case 10; and a first positioning auxiliary convex part 22 and a second positioning auxiliary convex part 23 arranged at an opposite side to the reference positioning convex part 21 while interposing the motor case, and restricting movement in the radial direction of the motor case. These first positioning auxiliary convex part 22 and the second positioning auxiliary convex part 23 are configured deformably, and a width between the reference positioning convex part 21 and the first positioning auxiliary convex part 22 and a width between the reference positioning convex part 21 and the second positioning auxiliary convex part 23 are set to be slightly narrower than a width of the motor case interposed therebetween.</p> |
