PURPOSE:To make engagement easy and accurate, by installing a clad piece doing elastic deflection to a clad block and a ring spring energizing expanding force to an engaging piece and this clad piece as well as installing a spring overexpansion preventing device solidly in an ornamental part as one body, in case of a plastric wheel cover for a vehicle. CONSTITUTION:Plural clad blocks 10 are installed in the inner part of a wheel cover ornamental part 2 at regular intervals. And, each clad block 10 is constituted of two engaged pieces 12, a clad piece 11 situated between these engaged pieces 12, and a ring spring 3 being interposed between the engaged piece 12 and the clad piece 11 and expanding this clad piece 11. And, an overexpansion stopping part 51 of the clad piece 12 is installed solidly together with the ornamental part 2 as one body. With this constitution, the clad piece 11 and the engaged piece 12 both are deflected by elasticity of high complinace, and slightly opened by elasticity of high stiffness, installing and engaging the ring spring 3. With this constitution, structural simplification and improvement in reliability for engagement are well promoted. |
