Abstract: A stationary portion of a motor includes a shaft component, an upper plate portion, and a lower plate portion. A rotating portion includes a sleeve portion which is disposed between the upper plate portion and the lower plate portion. The shaft component includes an inner shaft upper portion, an inner shaft lower portion which is located in a lower side of the inner shaft upper portion, and an outer shaft portion. The outer shaft portion is located on an outer circumferential surface of the inner shaft upper portion and an outer circumferential surface of the inner shaft lower portion. The inner shaft upper portion and the upper plate portion are preferably defined by a single monolithic member, and the inner shaft lower portion and the lower plate portion are preferably defined by a single monolithic member.

Abstract: A motor includes a stationary unit and a rotary unit. The stationary unit includes a stator, a base portion having at least one hole, and a flexible wiring substrate. The flexible wiring substrate reaches a position higher than a lower surface of the base portion through at least one hole and is arranged to supply electric power to the stator. The flexible wiring substrate includes a connection portion arranged higher than the lower surface of the base portion and connected to the stator. The connection portion includes a solder portion arranged on a lower surface thereof to cover a portion of a lead wire extending from a coil of the stator. At least a portion of the solder portion is positioned within the hole.
