Abstract
A fan suitable for use in a refrigerator includes a motor frame having a bracket insertion hole, a bracket including a cylindrical portion fitted into the bracket insertion hole so as to project from the motor frame and a bearing, a stator including a stator core, a stator coil wound on the stator core, and a molded layer molded from a synthetic resin so as to cover the stator core and the stator coil, the stator being disposed on an outer periphery of the cylindrical portion projecting from the bracket insertion hole so as to be supported by the cylindrical portion and the motor frame, a rotor including a rotational shaft inserted into the cylindrical portion so as to be rotatably mounted via the bearing on the bracket and having both ends, a rotor yoke disposed on one end of the shaft opposite to the motor frame so as to cover the stator, and a rotor magnet disposed on an inner circumferential face of the rotor yoke so as to be opposed to an outer circumferential face of the stator core with a gap between them, an impeller disposed on an outer circumference of the rotor yoke so as to be rotated with the rotor yoke, and a sealing cylindrical portion disposed on a circumferential edge of the bracket insertion hole so as to be integral with the motor frame, the sealing cylindrical portion being fitted into a space defined between the cylindrical portion of the bracket and the molded layer.
