<p>PROBLEM TO BE SOLVED: To provide a motor-driven centrifugal blower capable of easily forming a cut and removed portion in adjusting a rotational balance.SOLUTION: A motor-driven centrifugal blower and the like includes a motor, a rotating shaft 9, a diffuser air trunk portion 17, a hub 11, a plurality of rotary vanes 12, and a shroud 13. The hub 11 is formed so that its outer peripheral radius is agreed with an outer peripheral radius of the plurality of rotary vanes 12, and an inclined face formed under assumption that an edge portion at a rotary vane side, of a plurality of stationary vanes 7, an outer edge portion of the hub 11, and an outer edge portion of the shroud 13 are connected, is inclined in the direction to separate from the rotating shaft from the hub 11 side toward the shroud 13 side.</p> |
