<p>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.</p> |
