Abstract
A wheel cover for automobiles includes a main body which is composed of a thermoplastic synthetic resin material, and which is integrally provided on its rear surface with a plurality of reinforcing ribs projecting rearwardly of the main body. At least one of the reinforcing ribs has a hollow bottom portion adjacent to the rear surface of the main body, having a width which is greater than the thickness of the main body. The ribs with the hollow bottom portion serve to realize satisfactory rigidity and impact resistance of the wheel cover, without accompanying formation of undesirable sink mark on the front surface of the main body to deteriorate the appearance.
