CA 2650351

A vehicle wheel comprises an outer rim having a disk section formed by embossing a portion with a large plate thickness and a rim section formed by drawing a portion with a small plate thickness as a periphery of the disk section; and an inner rim with portions superimposed on prescribed positions of the disk section. Flange sections of both the outer and inner rims are formed in inward curled double shape. The outer and inner rims are integrated with each other by a weld with the superimposed portions superimposed and positioned on the prescribed positions. Since the double shape inward curl of the flange section is formed by pressing, the wheel is the strongest rim section. The disk section is formed by embossing, which increases strength even when it is a thin plate, yielding a lightweight wheel.
