PURPOSE:To prevent the release of a holder from an engagement section by making holder retaining space larger than the wire diameter of a holder relative with a base in an approximately vertical direction, and so forming at least two portions of the engagement section as to have different opening positions in the afore-said direction. CONSTITUTION:The engagement section 3 of a wheel cap is constituted with a leg 30 projected from the end of a rib 2, and the head 31 thereof. This head 31 is made to have three forms of A, B and C. Holder retaining space 5 is formed at a position enclosed with the first and second projections 32A and 33A of the head 31A, and the opening 50 of the holder retaining space 5 is formed between the tip of the second projection 33A and a guide surface 32a. The gap of the opening 50 is made slightly smaller than the wire diameter of a holder 4, and the vertical length of the holder retaining space 5 relative with a base 1 is made larger than the wire diameter of the holder 4. The head 31B has an opening section 50 at the center of the aforesaid retaining space 5, with the tips of the first and second projections 32B and 33B bent. Also, the first projection 32C of the head 31C is bent. The second projection 33C, however, is not bent and an opening section 50 is formed near the tip of the head 31C. |
