FIBER REINFORCED RESIN GEAR, METHOD OF FORMING FIBER REINFORCED RESIN GEAR BY INJECTION MOLDING, FIBER REINFORCED RESIN ROTARY BODY, METHOD OF FORMING FIBER REINFORCED RESIN ROTARY BODY BY INJECTION MOLDING

Plural ejector pins are made to project before a molten resin containing reinforcing fibers is injected into an inside of a cavity through pin point gates in a web forming portion in the inside of the cavity and at positions outside the pin point gates in a radial direction. The ejector pins are retracted from the inside of the cavity after a flow of the molten resin containing reinforcing fibers injected into the inside of the cavity through the pin point gates impinges on the ejector pins and is divided and before a tooth portion forming portion in the inside of the cavity is filled with the molten resin containing reinforcing fibers. Accordingly, weld lines which extend along the radial direction are formed at positions outside the ejector pins in the radial direction, and the molten resin is filled in portions formed after the ejector pins are retracted.
