PURPOSE:To improve the durability and reliability without effects of contamination by dust by providing a supporting body to stand in a wheel cover facing wheel threading nuts, engaging extended ear parts protruded from a star-like circular spring body with the supporting body, and holding the nuts by the extended ear parts. CONSTITUTION:A supporting plate 2 is provided standing in a wheel cover disc 1 and facing a nut 4 to be capable of oscillation by a hinge 21. In the meanwhile, a extended ears 32 are formed in a corresponding number to nuts 4 at a circular spring body 3 to be like a star, and the nut 4 is formed to hold it at a holding angle alpha while it is applied to an outline 40 of the nut 4 at an angle of beta. In this constitution, the extended ear 32 of the spring body 3 is fixed at a hole 22 of the supporting plate 2, and the nut 4 is held at an angular part. In this constitution, bad effects of contamination by dust can be eliminated, and the durability and reliability can be improved. |
