PURPOSE:To surely prevent the rotating movement relative to a wheel of a wheel cap by covering an antislipping member composed of a material which is softer than an engaging part engaging with the inner circumferential surface of the wheel and has a high frictional resistance on the side peripheral surface of said engaging part. CONSTITUTION:A wheel cap is formed of a disc base part 1 having valve ports 10, a plurality of engaging parts 2, 2' protruding in the direction parallel to the shaft and standing at circumferentially directional intervals in the peripheral part on the reverse side of the base 1, and antislipping members 3 provided in two engaging parts 2' positioned symmetrically about the center of the base part 1. A ring-form holder 4 having a plurality of loop parts 40 is held in each engaging part 2, 2'. The wheel cap is installed in a wheel by the elastic force of the holder 4. In this case, the antislipping member 3 is formed of a material softer than the engaging part 2' and having a high frictional resistance, and made to cover throughout the leg part 20 and head part 21 of the engaging part 2'. |
