Abstract:
A centrifugal fan according to a preferred embodiment of the present invention includes an impeller, a motor portion, and a housing. The housing includes an upper plate portion, a lower plate portion, and a side wall portion. The upper plate portion or the lower plate portion includes an air inlet. One of the upper and lower plate portions and the side wall portion together define a single housing component molded by casting. A portion of the one of the upper and lower plate portions which is along a boundary between the side wall portion and the one of the upper and lower plate portions defines an increased thickness portion arranged to have an axial thickness greater than that of a remaining portion of the one of the upper and lower plate portions.
