    摘要: A set of split bodies for forming a synthetic-resin blower fan through a hollow-article injection molding process, wherein the blower fan integrally includes a circular base, a cover portion having an air inlet opening at the center thereof, and a plurality of blades. The set of split bodies comprise a first split body including the circular base and a plurality of blade members, and a second split body defining the inner surface of the cover portion and having an outer surface on the opposite side of the first split body. The outer surface of the second split body is formed with a plurality of reservoirs each extending radially in alignment with the corresponding blade member of the first split body to define spaces to be filled with molten synthetic resin in a state where the first and second split bodies are assembled together.
