Abstract
In order to prolong the durability of a disk wheel which is determined by a dynamic radial fatigue test, the disk wheel for an automobile comprising a rim and a disk which are drop portion-engaged with each other, has a construction such that it includes a plurality of humps provided on an outer peripheral surface of the disk facing the rim, the humps being formed at positions away from welded portions between the disk and the rim in such a manner as to extend with intervals in the circumferential direction, so that the outer peripheral surfaces of the hump are press-fitted against the rim.
