Abstract (en)
A centrifugal fan 51 has an impeller 23 and a bell mouth 25. The bell mouth 25 has a plurality of wall parts 27 provided on an outer peripheral surface 25s of the bell mouth 25. The wall parts 27 are arranged at predetermined intervals on the outer peripheral surface 25s in a circumferential direction of the outer peripheral surface 25s. Each of the wall parts 27 extends along the outer peripheral surface 25s from the front side F to the rear side R in an axial direction A so as to be substantially parallel to the axial direction A and to a radial direction of the bell mouth 25.
