PROBLEM TO BE SOLVED: To provide an automobile wheel capable of realizing both its light weight and low cost while satisfying its durability performance. SOLUTION: This wheel disc 3 comprises disc flanges 11 intermittently formed along its circumferential direction, and inclined arcuate recess edges 20 inclined inwardly in respect to disc shoulders between the adjoining disc flanges 11. Boundaries 22, 22 between the inclined arcuate recess edges 20 and the disc flanges 11 form a fitted state with the wheel 2, so that the automobile wheel 1 realizes a sufficient durability and at the same time it is possible to attain a low cost and low weight by reducing an amount of material.
