    摘要： A thrust yoke is fixed into a second recessed portion of a base with adhesive. The second recessed portion has a first surface to be in contact with the bottom surface of the thrust yoke, and a second surface axially opposing the bottom surface of the thrust yoke with a gap therebetween. The thrust yoke has a bent portion at its radial end. The bent portion is bent downward. The thrust yoke also has a protruding portion extending downward from the bent portion. The protruding portion axially opposes the second surface of the second recessed portion of the base with a gap therebetween.

    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.
