Abstract
A wheel for an automobile is configured in such a manner that the wheel disc comprises an outer peripheral ring section having protrusions and recesses, the outer peripheral ring section being formed by continuously and alternately forming circular arc-shaped contact sections and contactless protrusion sections along the circumferential direction of the wheel, the circular arc-shaped contact sections being in contact with and welded to the bent peripheral section of the wheel rim, the contactless protrusion sections protruding further toward the front side than the circular arc-shaped contact sections and separating from the bent peripheral section. Welded sections at which the circular arc-shaped contact sections and the bent peripheral sections are welded together are intermittently arranged in the circumferential direction of the wheel. The configuration provides a large design surface to improve the freedom of design and improves the rigidity because of the shape effect of the outer peripheral ring section having protrusions and recesses.
