A vehicle wheel is of a three-piece sandwich type and high in accuracy and rigidity and can be manufactured less expensively and more efficiently. The radially outer portions of the flanges of an inner rim part and an outer rim part, which constitute a rim assembly for supporting a tire, are located in contact with each other outside the peripheral edge of a disk in the radial direction thereof so that the portions constitute a butted part. The rim parts are clamped to each other by bolts and nuts in such a manner that the radially inner portions of the flanges pinch the flange of the disk on both the sides of the latter flange. The butted part is provided with a welding seal on the peripheral surfaces of the flanges of the rim parts.
