PURPOSE: A structure for reducing the noise of an impeller for a vacuum cleaner motor is provided to reduce resonance noise by forming a plurality of resonance preventing holes communicated to suction spaces. CONSTITUTION: An impeller(17) for a vacuum cleaner motor includes a circular rear plate(17b) coupled to a rotary shaft, a front plate(17a) having an air inlet(17d), and a plurality of spiral blades(17c) installed between the front plate and the rear plate. A plurality of resonance preventing holes(17f) are formed at the circumference of the rear plate.
