PURPOSE:To obtain a wheel cover which are simply and precisely balanced as a whole, by providing, on the back side surface of the wheel, weight adjusting parts such as, for example, lightening holes and padding pieces, corresponding to a valve inserting hole. CONSTITUTION:A valve inserting hole 2 is formed in a body 1 by hollowing out or notching the plate wall of the body 1, and weight adjusting parts are provided on the back side surface of the body, for adjusting the weight of the body with the use of lightening holes 3a, 3b, 3c and padding pieces 4a, 4b, 4c, corresponding to the notching. This wheel cover thus formed, is well-balanced as a whole, due to the provision of the weight adjusting parts 3a, 3b, 3c, 4a, 4b, 4c which are equivalent in weight to the valve inserting hole 2, and the appearance of the wheel cover is never impaired since the weight adjusting parts are arranged on the back side surface. |
