Abstract
A motor includes a coming-off preventing portion including an inner circumferential edge defining a through hole, inside which a substantially cylindrical bearing housing is inserted, and being arranged axially above an insulator. The inner circumferential edge has at least two different radial dimensions. A boss portion includes a columnar portion inserted inside the through hole, and a collar portion extending radially outward from a lower end of the columnar portion. The collar portion includes an outside surface having at least two different radial dimensions, and an upper surface arranged axially opposite a bottom portion of the inner circumferential edge. The radial dimensions of the inner circumferential edge and those of the collar portion are arranged to allow the collar portion to be axially inserted through the inner circumferential edge only when the inner circumferential edge and the collar portion are arranged in a predetermined circumferential orientation relative to each other.
