    Abstract: A base portion of a motor includes an annular 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 are arranged to extend from the recessed portion toward land portions of a circuit board arranged on a lower surface of the base portion. A draw-out surface of the recessed portion has a lower opening of each of the at least one through hole defined therein. A wall surface of the recessed portion includes communicating openings each of which is in communication with one end of a separate one of the groove portions. Conducting wires are drawn out from coils arranged above the base portion to the draw-out surface through the at least one through hole, and are passed through the communicating openings and the groove portions to be soldered to the land portions. The recessed portion has a sealant arranged therein. The lower opening of 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 contributes to preventing the sealant arranged in the recessed portion from overflowing toward the land portions.

    Abstract: A spindle motor includes a base portion and a bearing mechanism. A fixing region, which includes a first region at which the base portion and the bearing mechanism are fixed to each other and a second region at which a seal gap is defined between the base portion and the bearing mechanism, is located between an inner circumferential portion of the base portion which defines a through hole and an outer circumferential portion of the bearing mechanism. The inner circumferential portion of the base portion has, at least in the second region, a degree of surface roughness greater than a degree of surface roughness of the outer circumferential portion of the bearing mechanism. The seal gap gradually decreases in radial width with increasing height, and includes an adhesive along an entire circumference of the seal gap.
