Abstract

PURPOSE:To decrease air resistance, to improve appearance, and to prevent entrance of contaminant, by a method wherein, in a title cover having spoke-like appearance, an opaque coating layer is formed on the outer surface of a cover body made of luminous metal plate, except a clear cover and a linear clear part. CONSTITUTION:The outer surface, around a projection 11a adapted to mount a discriminating mark 12 thereto, of a wheel cover body 11 formed in a gentlysloped conical disc and made of a luminous metal plate, such as stainless steel, is covered with a clear cover 13 to form a see-through part 13c. An opaque coating layer 17 is formed except plural non-coating part 16, extended radially from a center. This constitution causes light to be reflected by the cover body 11 through the non-coating part 16 and the clear cover 13 to provide spoke-like appearance, resulting in improvement of appearance. Further, this causes a surface to be smoothed, resulting in a decrease in air resistance.

A dark black coating film is formed on the remainder of the substrate 1a. The inner and outer covers 1 and 2 are concentrically stacked and fixed to the road wheel 3, giving it a spoke-like appearance.

[Problem that the invention seeks to solve]

1. In recent years, in order to minimize air resistance while driving, there has been a growing tendency for vehicle bodies to have flush (flattened) outer surfaces. However, - in the conventional wheel cover mentioned above, the spokes are exposed on the outer surface, so as the road wheel rotates, air flow turbulence occurs around the wheel cover, increasing air resistance, and the spokes are exposed on the outer surface. There is a problem in that dirt such as dirt and dust easily adheres to the parts, and it is difficult to wash away the adhering dirt with ordinary water washing.

[Means for solving problems]

This invention is intended to solve the problem described in item 1. The outer surface of the wheel cover body, which is formed into a substantially disk shape from a bright metal plate, is covered with a transparent cover, and the outer surface is covered with linear lines extending radially. By leaving an uncoated area and forming an opaque coating layer, the outer surface of the wheel cover becomes flush, reducing air resistance, and preventing mud and dirt from being seen from the outer surface of the wheel cover. To provide a wheel cover for a vehicle that exhibits a refined appearance.

This invention includes a wheel cover body formed in a substantially disc shape from a bright metal plate, a transparent cover provided to cover the outer surface of the wheel cover body, and a transparent cover provided on the outer surface of the transparent cover from the center side. This vehicle wheel cover is characterized by comprising an opaque coating layer formed so as to leave linear non-coated portions extending radially around the periphery.

[For production]

The vehicle wheel cover configured as described above is used by being attached to the road wheel of a vehicle with the wheel cover body facing inside. When in use, the metallic shiny surface of the wheel cover body is visible from the outside through the radial uncoated parts and the transparent cover, giving it an excellent spoke-like appearance. And since the outer surface of the transparent cover is formed smooth,
No air turbulence occurs. In addition, mud, dirt, etc. are not visible from the outside, and an excellent appearance can be maintained for a long period of time.
