PROBLEM TO BE SOLVED: To provide a cover which can be exchangeably used for steel and aluminum wheels. SOLUTION: A tubular protrusion 50 is formed on the back surface of a decorative wheel. The tubular protrusion 50 can be mounted on a lug nut of a vehicle at its tip portion. Slits of a certain length are formed on several places from the tip of the protrusion, and an annular undercut protruding inward is formed on the tip. On the inner surface of the protrusion, a reinforcing rib 60 is formed from the protrusion root up to the tip. A groove to retain the lug nut is formed between the rib end and the undercut. |
