Abstract
A vehicle wheel according to the present invention includes a hollow-state hollow portion and a solid-state non-hollow portion inside an outboard bead seat in a radial direction, which are provided in series in a circumferential direction of the wheel, the non-hollow portion having a cross section with a larger area than a hole cross section of a valve hole and having the valve hole formed therein. This structure prevents a sealing structure for ensuring hermetic performance from being complicated as compared to a wheel having the valve hole in the hollow portion, thus simplifying a mounting structure of an air valve. A method for manufacturing such a vehicle wheel allows formation of the valve hole in the non-hollow portion. Machining dust generated through a cutting process can thus be prevented from entering the hollow portion and remaining therein.
