PROBLEM TO BE SOLVED: To provide an electric blower with superior rotational balance.SOLUTION: A centrifugal fan and washers 63, 64 are formed integrally with each other by powder coating. The centrifugal fan and the washers 63, 64 are rotationally balanced integrally. The centrifugal fan is fixed to the rotating shaft 34 of a motor by inserting the rotating shaft 34 into the centrifugal fan and holding a lower fan plate 56 by the washers 63, 64. Consequently, the electric blower with a superior rotational balance can be provided. |
