となっている。2. Description of the Related Art In an automobile wheel, a disc is press-fitted onto the inner peripheral surface of a bead seat portion of a rim, and the disc is welded.
In a two-piece wheel joined to a body, a disk formed with a plurality of spokes excellent in design is now partially adopted from an all-circumference weld type disk. Since the disk on which such spokes are formed is welded to the rim at the spokes, the overall welding length is shortened, and it is an important requirement to improve the strength, especially the durability of the welded portion.

問題がある。SUMMARY OF THE INVENTION The aforementioned Japanese Utility Model Laid-Open No. 6-55.
According to the conventional technique described in Japanese Patent Application Publication No. 802, although the effect of improving the welded part durability is obtained to some extent, the strength is slightly improved and remains insufficient. The reason is that the rim bead seat portion 105 is a portion that receives the load of the wheel, and providing a joint portion by welding at that portion directly receives the high stress, and has a problem in durability.

が形成されることは耐久強度が低下する。The rim hump portion 108 is usually a small-diameter R-shaped portion, and since this portion is formed by roll forming (plastic working) in rim production, a reduction in the thickness of this portion is inevitable. The formation of a welded joint in a thin part of the steel reduces the durability.
