Abstract
In a motor, a stationary portion includes a shaft portion and an upper thrust portion arranged to define a single continuous monolithic member together with the shaft portion, and arranged to extend radially outward from an upper portion of the shaft portion. The shaft portion includes a female screw portion recessed axially downward from an upper end thereof. An upper end of the single continuous monolithic member defined by the shaft portion and the upper thrust portion includes an upper end annular surface arranged to extend radially outward from the female screw portion perpendicularly or substantially perpendicularly to the central axis. An outside diameter of the upper end annular surface is greater than a diameter of an outer circumferential surface of the shaft portion.
