Abstract
A base member of a motor includes a base through-hole extending through a bottom portion thereof. Two or more lead wires extending from coils pass through the base through-hole. Thus, as compared with a case where the lead wires pass through different base through-holes respectively, it is possible to reduce the number of the base through-holes. Accordingly, it is possible to minimize or prevent a reduction in the rigidity of the base member. Insulating sheet portions are arranged on the lower and upper surfaces of the base member. Each insulating sheet portion includes an overhang portion which overlaps with the base through-hole when seen in a plan view. The lead wires extending from the coils are led out toward the lower surface of the base member through holes, cutouts, or slits defined in the overhang portion. This makes it possible to easily distinguish the led-out lead wires from each other.
