Composite structure rotating body and resin molded body
By setting thin-walled concave regions and recesses in the resin molded body, the problem of uneven distribution of reinforcing fibers in resin composite rotating bodies is solved, achieving strength balance and cost control. It is applicable to composite rotating bodies and resin molded bodies.

AI Technical Summary
During the molding process of resin-based composite rotating bodies, reinforcing fibers have difficulty following certain areas of the resin molded body, especially the convex areas in adjacent concave and convex shapes, resulting in uneven strength.
Multiple concave regions are formed circumferentially in the resin molded body, and thin-walled portions are provided in the concave regions. The total depth of the concave portions on both sides is less than the thickness of the thin-walled portions, ensuring that the reinforcing fibers can be evenly distributed. This is combined with metal bushings and resin components to improve strength.
By balancing the reinforcing fibers, the overall strength of the composite rotating body was improved, and the reduced bonding between the resin molded body and the bonded resin components was suppressed, thus achieving both strength balance and cost control.
