Gear-shaped resin sheets Sa are laminated such that tooth portionsare aligned in an axial direction, thereby preparing a spur gear-shaped net-shape body Tooth portions of the resin gear formed in a lower dieare pressed in a helical tooth-shaped molding space to deform the tooth portionsof the net-shape bodyinto a helical tooth tilted relative to the axial direction, and the direction of reinforcement fibers at the tooth portionsof the molded resin gearis tilted relative to the axial direction.

Resin gear, and method and apparatus for producing the same

A resin rotating bodyis configured by a ring-shaped resin ring, and a metallic bushwhich is fitted to an inner circumferential surfaceof the resin ring, and projectionsas rotation preventing means that connects the resin ring and the metallic bush so that the resin ring and the metallic bush do not rotate with respect to each other are provided on an outer circumferential surface of the metallic bush. Projections of the metallic bush are further provided at positions eccentric forward in a press-fitting direction of the metallic bush from a center in the axial direction of the metallic bush.
