Claims

[Claims for Utility Model Registration] A two-piece steel wheel in which a steel disk whose outer periphery is shaped like a rim flange and a steel rim having a rim bead seat at one end and a rim flange at the other end are welded together. In the disc, the outer circumferential portion is formed to have a thickness comparable to that of the rim, and has a rim fitting step portion on the back side of the outer circumferential portion that fits with the inner circumferential surface of the rim. The rim has a rim bead seat end extending substantially straight in the axial direction, and the rim has a rim bead seat end that is in contact with a back surface of an outer peripheral portion of the disk. A two-piece steel wheel, characterized in that the inner circumferential surface of the end of the rim bead seat is welded to the disc while being fitted into the rim fitting step.
