PURPOSE:To obtain predetermined strength by eliminating the cutting of a fiber, by winding a continuous fiber bundle impregnated with a resin in an amount of 70$85% based on a predetermined winding amount around a cylindrical insert jig under low tension and subsequently winding the remaining fiber bundle therearound under high tension while the previously wound fiber bundle is pressed. CONSTITUTION:At first, a fiber bundle 1 is wound around the groove 2a of a jig 2 to mold a ring part 5 and subsequently wound around an insert metal jig 4 to mold a spork part 6. Tension is applied at the winding time of the ring part 5 but, when the fiber bundle 1 is transferred from the ring part 5 to the spork part 6 or, contrarily, when from the spork part 6 to the ring part 5, each fiber is bent at an angle of almost 90 deg.C and, therefore, high tension can not applied to the fiber bundle 1 wound around the bent part. That is, the fiber bundle 1, to which low tension was applied, is wound around the insert metal jig 4 by the prescribed number of times to form the spork part 6 and the fiber bundle 1', to which high tension was applied, is wound around the fiber bundle 1 between flanges 7 of the metal jig 4 while the base part of the spork part 6 is pressed. When the fiber bundle 1' is wound 5-20 times by this method, the spoke base part 8 is compressed to generate bonding strength between the base part 8 and the insert metal jig 4.
