The present invention relates to a non-rotating wheel cap which is inserted at the center of a wheel rim using fixtures. The cap is used to display printed or adhered decorations that remain stationary in an upright position, while the rim is rotating. The preferred embodiment of the present invention comprises: a plurality of fixtures (2) extending from the body of a hollow disk-shaped housing (1), a small shaft (3) extending from the center of the housing body, a roller bearing (6); wherein such bearing is press-fitted into a semi-disk omega-shaped weight (4) from one of its faces; wherein the opposite face of such semi-disk omega-shaped weight is engraved with small cylindrical holes (7); and wherein an outer disk-shaped cover (9) is attached to such weight. The cap is also simple in design, since it needs only one roller bearing and includes no bolts or adhesives.
