ABSTRACT:
Provided is a brushless-motor fan unit having a centrifugal fan and a scroll casing enclosing the centrifugal fan therein. The rotor of the brushless-motor is carried by the centrifugal fan. Further, the motor shaft carrying the centrifugal fan is supported at its front and rear ends by the scroll casing. With this construction, the motor housing can be eliminated so as to obtain a compact centrifugal type motor fan unit in a small thickness as a whole.
