<p><P>PROBLEM TO BE SOLVED: To provide a vehicular wheel produced with high productivity, reduced in weld failure and having sufficient joint strength. <P>SOLUTION: This vehicular wheel is structured by welding a rim 2 and a disk 10 together. The rim 2 has a drop part, and the disk 10 is integrally formed of a plate material. The disk has a hub installation part 10a, a plurality of spokes 10b radially extending from the hub installation part toward the outer peripheral edge of the disk, and a ring-shaped disk flange 10c connected to the spokes through a curved surface connection part R, which is formed by folding back the outer peripheral edge of the spokes in the axial direction of the wheel. The disk flange is extended along the axial direction of the wheel, and a part surrounded by the adjacent spokes, the hub installation part and the disk flange is defined as a decoration hole 20. Among the parts where the inner peripheral surface of the rim and the outer peripheral surface of the disk flange are fitted to each other, parts facing tips 12 of the spokes are welded. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
