    • A small-sized motor includes a field magnet attached to an inner circumferential surface of a metallic motor casing and having four or more magnetic poles. The field magnet is formed of a single ring-shaped magnet member having a predetermined thickness with respect to the radial direction and a predetermined length with respect to the thrust direction. At each of portions between the magnetic poles formed through magnetization, the magnet member has a thin portion having a reduced thickness with respect to the radial direction, the thin portion being formed by cutting the magnet member from the radially outward side. The magnetization is performed in the radial direction so as to alternately form S poles and N poles in the circumferential direction. At each of portions between the magnetic poles, the magnet member may have cut portions formed at opposite end portions of the magnet member with respect to the thrust direction.

    • A manufacturing method for a diffuser comprises a first process of forming a first molded component, by gradually forging a cylindrical solid material having fiber flow extending in an axial direction from an axial direction thereof, the first molded component including a flange section having a central hole section, and a bottomed cylindrical section having a communication hole leading to one end, in the axial direction, of the flange, and communicating with the hole section, and having fiber flow that is flowing substantially in the axial direction without being cut, and a second process of forming a second molded component, by split molding a peripheral groove using split dies at the outer periphery of the bottomed cylindrical section of the first molded component, including a flange having a central hole section, and a bottomed cylindrical section having a communication hole leading to one end, in the axial direction, of the flange, and communicating with the hole section, and having the peripheral groove formed without cutting fiber flow. The embodiment provides a manufacturing method for a diffuser that can be produced with high yield and at low cost, while doing away with locations where fiber flow is cut and that has no gas leakage.
