Abstract: The present invention relates to a fan frame structure including a plastic frame and a metal fixing frame, in which at least two support arms are disposed on the rim of the fixing frame and extended outwardly therefrom, the outwardly extended distance of each support arm shall be beyond the range of an accommodation space of the frame, the portion of the support arm beyond the accommodation space in integrally enclosed by the plastic material of the frame. Therefore, the present invention not only significantly lowers the material cost, but also produces a variety of products in coordination with various specifications of fixing frame by using a single injection mold for the frame to save the mold cost.
