Abstract: PURPOSE: A plastic hub and a method for fabricating the same are provided to reduce the noise by forming a central insert and a conical insert and injection-molding the central insert and the conical insert with using thermoplastic resin. CONSTITUTION: A pair of inserts(12,13) are formed in thermoplastic resin(11) so as to form a hub(10). The hub(10) includes a central portion to which a cam shaft is press-fitted, and a conical portion. The inserts(12,13) are inserted into the central portion and the conical portion of the hub(10). The central portion of the hub(10) is formed in a cylindrical shape and the remaining portion of the hub(10) is formed in a frustum shape. A plurality of perforating holes(14) are formed in the conical portion of the hub(10). The perforation holes(14) allow resin to easily flow when an injection molding process is carried out.
