Among these methods, the method that can improve the design of the aluminum wheel most is surface treatment by plating.
JP-A-9-226301

However, there are the following problems in the method for improving the design by the conventional surface treatment method using plating.
Since the entire aluminum wheel design surface is brilliantly treated, the design surface becomes a monotonous brilliant surface, lacks novelty, and lacks design.
Since the aluminum wheel is heavy, it is not easy to handle the aluminum wheel during the plating operation, and the design surface has an uneven surface, so that it is difficult to perform plating compared to flat plating. Therefore, the plating becomes expensive. Moreover, once the design surface is damaged, the entire wheel needs to be replaced, which is not economical. A decorative member into which resin is poured as in Japanese Patent Application Laid-Open No. 9-226301 (not plated) is not economical because the decorative member is not interchangeable once it is damaged.
Moreover, if a stealing is performed by providing a bold recess on the design surface, it is difficult to provide a bold recess on the design surface because it impairs the design and makes plating difficult, resulting in a reduction in weight. difficult.
In addition, when using a decorative member, fix the decorative member to the aluminum wheel so that at least one of the following is satisfied: It is hoped that it can be done.

Since the decorative member 30 is detachably mounted and the design surface 19 is configured by the cooperation of the aluminum wheel 11 and the decorative member 30, the entire design surface is decorated by decorating only the decorative member 30 portion. Compared to the case of decoration, the design is not monotonous, and novelty appears and the design is improved.
In addition, the surface of only the decorative member 30 is surface-treated, so that the glittering surface is reduced compared to the case where the entire surface is surface-treated, and only the decorative member 30 is replaced even if the decorative member 30 is damaged. Because it can be done, the economy is improved.
In addition, since the decorative member 30 is mounted on the recess 20 and the recess bottom surface 26 is not visible from the front, it is possible to boldly steal (remove meat) when forming the recess 20 and to reduce the weight of the wheel.

Since the surface of the decorative member 30 is subjected to surface treatment and the surface of the aluminum wheel 11 is not subjected to surface treatment, the surface of the design surface of the aluminum wheel 11 is subjected to surface treatment (such as bright plating). The processing area is reduced, and the work is facilitated and the economy is improved. Further, the surface treatment on the lightweight decorative member 30 is easy to handle.
