PROBLEM TO BE SOLVED: To provide an automobile wheel capable of suppressing water and sand from being accumulated in an inner peripheral vacant area formed inside a bead sheet on a front side of a wheel rim. SOLUTION: In the automotive wheel, a fitting outer peripheral part 24 formed at an outer peripheral edge of a wheel disc 3 is internally fitted to a rim flange 11 on a front side of the wheel rim 2 and welded from a back side to be integrated. The wheel disc 3 is constituted so that a plurality of water removal recesses 25 reaching an inner side more than an inner peripheral surface 13a of the front side bead sheet part 13 from an outer end of the fitting outer peripheral part 24 are arranged in a circumferential direction. By the water removal recesses 25, water and sand intruded into the bead sheet inner peripheral vacant area 29 formed inside the front side bead sheet 13 can be discharged. Furthermore, since the fitting outer peripheral part 24 easily becomes flexible between the water removal recesses 25, it is easily fitted to the front side rim flange 11 and the generation of strain can be suppressed. Therefore, high durability can be exhibited. COPYRIGHT: (C)2009,JPO&INPIT
