摘要： A spindle motor includes a stator unit and a rotor unit supported to be rotatable with respect to the stator unit. The stator unit includes a stator, a base portion including a through hole, and a circuit board. The circuit board includes a connection portion to which a conductive wire from the stator is connected after passing through the through hole. A lower surface of the base portion includes a central region, a peripheral region, a recess portion, and a protrusion. A position of a distal portion of the protrusion is provided at a level higher than a level of a lowermost surface region of the central region and lower than a level of a bottom surface of the recess portion in a direction parallel or substantially parallel to a central axis.

摘要： A motor includes a stator and a rotor including a disk portion, a cylindrical portion, and a stopper. The stopper includes a stopper protruding portion and is fixed to an inner surface of the cylindrical portion. The cylindrical portion includes a cylindrical portion protruding portion that opposes an outer surface of the stopper. Adhesive is included between the cylindrical portion and the stopper. A gap between an upper end portion of the outer surface of the stopper and an inner peripheral surface of the cylindrical portion protruding portion defines a first tapered gap. A gap between a lower end portion of the outer surface of the stopper and an inner peripheral surface of the cylindrical portion defines a second tapered gap. The adhesive is included in the first tapered gap and the second tapered gap. The stator includes an annular or substantially annular surface below the second tapered gap.
