  "textContent": "In an automobile wheel, a disc flange of a wheel disc includes bent surface-side edge portions each having an arcuate shape and arranged concentrically with each other, and the bent surface-side edge portions extend from the surface-side end edge of a fitted straight annular portion to be bent radially inward and are dented to a back side of the outer end portions of the lateral edge portions of spokes. The thus configured automobile wheel can exhibit high strength and rigidity against a radial load, a bending load, and a torsional load because of the shape of the bent surface-side edge portions, thereby suppressing deformation of the disc flange caused while an automobile is running. Thus, it is possible to mitigate a stress concentration on a joined portion between the wheel disc and a wheel rim.",
