Abstract
A composite structure gear includes a ring-shaped resin molded body containing reinforcing fiber and resin and having tooth profiles formed on an outer peripheral portion, a ring-shaped metal bush, and a bonding resin member that bonds the resin molded body and the metal bush. In the resin molded body, a plurality of recessed regions are formed at predetermined intervals in a circumferential direction, and a thin portion in which recessed portions are formed on both surfaces in a thickness direction of the resin molded body is provided the recessed region. In the recessed region, a total value of depths of the recessed portions on both surfaces is smaller than a thickness of the thin portion.
