Abstract
A motor includes a shaft component, an upper plate portion, a lower plate portion, and a sleeve portion. The shaft component includes an inner shaft portion and an outer shaft portion. The upper plate portion defines a single monolithic member with one of the inner shaft portion and the outer shaft portion. The lower plate portion defines a single monolithic member with the other of the inner shaft portion and the outer shaft portion. The sleeve portion is disposed between the upper plate portion and the lower plate portion. A radial gap is defined between the sleeve portion and the outer shaft portion. A fixing range in which the outer shaft portion and the inner shaft portion radially overlap is arranged. At least a portion in an axial direction of the fixing range radially overlaps with an existing range in the axial direction of the radial gap.
