PROBLEM TO BE SOLVED: To provide a wheel cap of a structure having a fastening means in place of a conventional spring means, easy to mount, and difficult to come off. SOLUTION: Simple protrusions 4, 7 integrally formed with a cap body are adopted in place of the conventional spring means. A first protrusion (an engaging protrusion) 4 for engaging with a circumferential groove 9 of a wheel hub 8a and a second protrusion (a cap circumferential wall deforming preventive protrusion) 7 abutting on an outer surface of a circumferential wall of the wheel hub are alternately formed on an inner surface of a circumferential wall of the cap. In mounting the wheel cap 1 to the wheel hub 8a, the second protrusion 7 is brought into press-contact with the outer surface of the circumferential wall of the wheel hub at the moment of engaging the first protrusion 4 with the circumferential groove 9 of the wheel hub 8a. |
