PROBLEM TO BE SOLVED: To provide a balance correction device for an electrically driven blower, which can enhance the accuracy of a rotational balance due to the combination of a commutater motor with a centrifugal impeller. SOLUTION: When a centrifugal impeller 9 is to be mounted to the rotating shaft 15 of a rotor 4, a disc shaped balance correction member 20 is assembled between the centrifugal impeller 9 and a nut 16, a rotation balance is corrected by way of drill or a dispenser through an air intake port 22, so that vibration and noise can be lowered down, and the reliability of a motor can be enhanced much.
