Patent ID: 8914977

Claim:
A method for manufacturing a vehicle wheel having a rim including outboard and inboard bead seats for supporting a bead of a tire and a valve hole provided inside in a radial direction of the outboard bead seat for mounting an air valve, the method comprising the steps of: forming an annular vertical wall which protrudes outward in the radial direction from an outer surface of the rim throughout the whole circumference, and forming a protruding portion which protrudes outward in the radial direction from the outer surface of the rim and has a larger cross section than a hole cross section of the valve hole and a recessed portion which has a smaller outer diameter than the protruding portion between an outboard flange and the vertical wall in series in a circumferential direction of the wheel; forming the outboard bead seat configured with a bent vertical wall formed by bending the vertical wall toward the outboard flange and joining an end portion of the vertical wall to the outboard flange throughout a whole circumference, a hollow-state hollow portion configured with the bent vertical wall and the recessed portion, and a solid-state non-hollow portion configured with the protruding portion; and forming the valve hole in the non-hollow portion by a cutting process, the steps being sequentially conducted.
