Claims

[Scope of utility model registration request]

The impeller is attached directly to the main shaft of the motor that rotates at high speed, the main shaft is passed through the suction side of the impeller, and the shaft end is supported by a bearing cover that is fixed inside the suction pipe. A conical bearing having a stepped portion having a conical tip is provided at the end portion of the shaft so that it can be extracted from the bearing cover in the axial direction through the bearing cover, and the stepped portion is inserted into the bearing cover. A bearing for a blower that is directly connected to an electric motor.
