PROBLEM TO BE SOLVED: To obtain a motor fan restraining vibration upon operation. SOLUTION: This motor-fan 3 has a wind rectifier 13 in a synthetic resin on which a fan cover 32 of a blast part 12 is fitted by fixing with a frame 22 of the motor part 11. A supporting part 35 for forming a groove 34 between an outer peripheral surface 13c is integrated and provided at the wind rectifier 13. An opening edge part 32c of a fitting tubular part 32d of the fan cover 32 is pressed in the groove 34, and the fitting tubular part 32d is supported by the supporting part 35 from a diametrical direction outer side of the wind rectifier 13. Therefore, the supporting part 35 presses the fitting tubular part 32c of the fan cover 32 in a diameter contracting direction as the wind rectifier 13 contracts in the diametrical direction with the passage of time, and mutual relation between the fitting tubular part 32d of the fan cover 32 and the outer peripheral surface 13c of the wind rectifier 13 is kept constant.
