ABSTRACT:
A fan housing assembly includes a mounting base formed with a through hole thereon and a bushing. The bushing has a sleeve and is coupled to the mounting base by connecting the sleeve to the through hole. The mounting base and the bushing can be separately formed with predetermined materials in view of the different quality requirements before being assembled, thus resulting in lower manufacturing cost and enhanced flexibility in the fan design.
