PURPOSE:To make a decorative part unpeelable so easily by a car washing brush or the like, by bulging a portion of a lining part outside through a hole installed in an outer cap, while making up the decorative part with this bulged part. CONSTITUTION:A hub cap body 1, as a whole, is made up of a two-layer construction comprising an outer cap part 33 and a lining part 34, while a concave part 23 and a concave groove 24 corresponding to the pattern of each decorative part are formed on the head surface of the outer cap part 33 and further through holes 25 and 25 are formed on each bottom of the concave part 23 and the concave groove 24. At the head part, the lining part 34 is bulged to both inner parts of the concave part 23 and the concave groove 24 and filled in them 23 and 24. As for materials, those specified are used, that is, one being excellent in tipping resistance for the outer cap part 33 and the other excellent in both of elastic strength and creep resistance for the lining part 34 respectively, and the coloration of the outer lining part 34 differs from the outer cap part 33 in a hue, meaning that it is colored with optimum hues for decoration's sake. |
