摘要

A wheel cover provided with a pre-loaded spring mechanism wherein a plurality of inner and outer prop-like stopper ribs are arranged integral along the circumferential rim of the wheel cover on the backside thereof, said wheel cover being made of synthetic resin, and a spring which can be expanded wider than the interval between the inner and outer stopper ribs is fitted between the inner and outer stopper ribs, whereby the interval between the inner and outer stopper ribs can be usually kept certain to provide a pre-loaded spring force for fixing the wheel cover to the rim of a disc wheel.
