Center hub cap for vehicle wheels

Abstract From the Canadian patent

A center hub cap for vehicle wheels includes a dish-like main body of a synthetic resin material as, well as hollow and substantially cylindrical projections and retainer legs. These projections and legs are both formed integrally with the main body to protrude axially inwardly from the inner surface of the main body and, arranged alternately with each other. The projections radially support an annular spring ring for urging the retainer legs radially outwardly toward the inner peripheral wall of a recessed center portion of the wheel, and are provided with shoulder portions to axially maintain the spring ring in engagement with the retainer legs.
