摘要： A base unit for use in a storage disk drive apparatus includes a base portion; a stator core including a plurality of teeth; U-phase, V-phase, and W-phase coils; U-phase, V-phase, and W-phase common wires; and a circuit board. The U-phase, V-phase, and W-phase coils are wound on the teeth and arranged to define a U phase, a V phase, and a W phase, respectively. The U-phase, V-phase, and W-phase common wires are arranged to define the U phase, the V phase, and the W phase, respectively. Each of the U-phase, V-phase, and W-phase common wires is arranged to pass through a separate one of through holes to be drawn out beyond a lower surface of the base portion and electrically connected to the circuit board. Each of the through holes is sealed with a sealant such that the base unit is airtight.

摘要： A spindle motor includes a stationary portion, a bearing mechanism, and a rotating portion. The bearing mechanism is attached to the stationary portion. The stationary portion includes a base portion, a stator, and a wiring. The base portion is arranged to define a portion of a housing of the disk drive apparatus, the housing defining an airtight interior space. The base portion includes a recessed portion defined on a side thereof where the interior space is defined. The recessed portion includes an inner side surface including an adhesion region and a press-fit region. A lower portion of the bearing mechanism is fixed to the adhesion region through an adhesive, and press fitted to the press-fit region. An axial dimension of the adhesion region is arranged to be greater than that of the press-fit region.

摘要： A spindle motor includes a shaft arranged to extend in an axial direction, and a base portion arranged to define a portion of a housing, and including a through hole in which the shaft is inserted. A fixing region is defined between an inner circumferential portion of the base portion and a lower portion of the shaft. The fixing region includes a press-fitting region and an adhesion region defined on a lower side of the press-fitting region and in which a seal gap is defined between the inner circumferential portion of the base portion and the lower portion of the shaft. The seal gap is arranged to gradually decrease in radial width with increasing height. The seal gap is arranged to include an adhesive arranged therein over an entire circumference thereof.
