MOTOR FAN

PROBLEM TO BE SOLVED: To provide a motor fan capable of preventing deficient operation by inhibiting bending of a diffuser when the motor fan is operated. SOLUTION: A blower part 1 of the motor fan consists of a fan cover 2, a fan 3 and the diffuser 4 from the front. A motor part 5 comprises a stator core 6, a coil winding frame 7 of the stator, a bracket 8, a commutator 10, and a brush 11, etc. The blower part 1 and the motor part 5 are integrally formed to constitute the motor fan. When the motor part 5 is built in the motor fan, supports 14 disposed at four corners in the edge of the winding frame 7 abut to the diffuser 4, and bending of the diffuser 4 is inhibited. Therefore, the fan 3 is prevented from being pushed forward by the bending, and contact of the fan 3 and the fan cover 2 at a fan intake is avoided, so that the most deficient operation such as being locked can be prevented.
