Abstract
It is an object of the present invention to provide a wheel rim equipped with rim flanges that show no deformation or damage even though a reduction in weight is achieved. The wheel is equipped with rim flanges consisting of a double structure in which the end portions across the rim part of width of the rim are folded back to the inside and caused to contact the non-folded portions B in a state in which there is no gap. The abovementioned folded portions A and non-folded portions B have respective thicknesses that are greater than the thickness D of the rim part, and curved parts C that are smoothly continuous with the surfaces of the non-folded portions B are provided on the free end portions of the folded portions A.
