PURPOSE:To prevent the release of a holder from an engagement section by providing a projection in a direction from the second restriction surface for forming holder retaining space to the first restriction surface for covering a part of the aforesaid space, and further forming an oblique surface gradually sloped in a radial inward direction toward the tip of the head of a leg extended from a rib. CONSTITUTION:The engagement section 3 of a wheel cap is constituted with a leg 30 extended from a rib 2, and the head section 31 thereof. The first projection 32 of the head section 31 has the first restriction surface 51 approximately in parallel to the reverse side of a base 1, and the second projection 33 is radially projected inward to have the second restriction surface 52 approximately in parallel to the first restriction surface 51. In addition, the second projection 33 has a projection section 6 bent toward the first projection 32. Furthermore, holder retaining space 5 is formed at a position enclosed with the first restriction surface 51 and the second restriction surface 52, and the opening 50 of the space 5 is formed between the tip of the projection section 6 and the first restriction surface 51. In this case, the open end of the opening 50 is made slightly smaller than the wire diameter of a holder 4, while a gap between the first and second restriction surfaces 51 and 52 is made larger then the wire diameter of the holder 4. |
