The rib is formed by injection molding using a rib that is formed to protrude from a predetermined position on the inner surface side of the cover body as a pushing portion by a protruding pin when the cover body is removed from the mold. A concave portion is provided on the outer surface of the cover body corresponding to the protruding position of, and a rough surface is provided on the inner surface of the concave portion, and a colored transparent or colorless transparent protective film is provided on the outer surface of the cover body including the rough surface. It is configured by providing.

視認し難くすることができる。Function In this vehicle synthetic resin wheel cover, a concave portion is provided on the outer surface of the cover body, and a protective coating is provided on the outer surface of the cover body including the rough surface provided on the inner surface of the concave portion. It is possible to prevent the protective film from peeling off because the external force of the car wash brush is hard to act. Even if the cover body and the protective coating are made of a transparent synthetic resin, the rough surface is provided on the outer surface of the cover body at a position corresponding to the rib integrally molded with the cover body, so that the transparent body is transparent. By changing the bending transmittance through the synthetic resin cover body and the protective coating, the color tone changes due to the change in the wall thickness due to the ribs, or the imprint of the ribs due to the protruding pin when the cover body is released from the outer surface side. It can be difficult to see.
