（産業上の利用分野）
本発明は、最近、乗用車用として、流行し始めたワイヤ

ちエンボス部のエアーシール方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of air sealing the wire spoke wheel portions, ie, the embossed portions, of wire spoke wheels that have recently become popular for use in passenger cars.

られていた。(Prior Art) Conventional wire spoke wheels had a structure as shown in FIG. The wire spoke wheel portion and the embossed portion were filled with a single layer of sealing material as shown in FIG.
（発明が解決しようとする問題点）

に発生する相対動きに追従する柔軟性を合せもつことが
必要である。(Problem to be solved by the invention) Wire spoke mounting holes (hereinafter referred to as embossed parts)
It goes without saying that the sealing material is required to have strong adhesion to the wheel components, but it also has resistance to wear and tear caused by movement of the tire bead during use, and resistance to spoke-nipple and knee 2. It is also necessary to have flexibility to follow the relative movement that occurs between pull and embossing.

が損耗し易く又は引き裂かれ易く、さらにタイヤ脱着が

る引き裂きを受は易くなり、同じくエアシール機能が保
持されにくい欠点がある。However, if the tires are worn out or torn due to the movement of the tire bead during use, or if the tire is repeatedly attached and detached, cracks are likely to occur in the sealing material due to the relative movement between the posts due to the rubbing of the tire. There is a drawback that the air seal function is difficult to maintain, and in order to avoid the occurrence of cracks, the elastic modulus is 1×lO~I
When a soft sealing material of 109 dyne/crn" is used, the sealing material tends to be easily worn out or torn due to the movement of the tire bead during use, and even when the tire is repeatedly attached and detached, tearing occurs due to the rubbing of the tire bead. This also has the disadvantage that the air seal function is difficult to maintain.

The problem was solved by an air sealing method for wire spoke wheels in which air sealing is performed using at least two layers of sealing material, and the elastic modulus of the inner layer sealing material is lower than the elastic modulus of the surface layer sealing material.
