Abstract
A base portion of a motor includes an inner bottom plate portion, a recessed portion and groove portions recessed upward from a lower surface of the inner bottom plate portion, and at least one through hole passing through the inner bottom plate portion in an axial direction. The groove portions extend from the recessed portion toward land portions of a circuit board on a lower surface of the base portion. Conducting wires are drawn out from coils above the base portion to a draw-out surface through the at least one through hole, and are passed through communicating openings and the groove portions to be soldered to the land portions. Each of the at least one through hole is covered with the sealant. Drawing the conducting wires out of the recessed portion through the groove portions prevents the sealant in the recessed portion from overflowing toward the land portions.
