ABSTRACT:
A wheel shaping apparatus including a single cotter for expanding first and second dies circumferentially split into a plurality of first and second die elements, respectively. The single cotter is supported by a cotter supporting member at one end portion of the cotter and is also supported by a cotter guide at the other end portion of the cotter during shaping of a rim element. Because of the single cotter supported at both end portions thereof, rim bead seat portions located at axially end portions of the rim element are shaped in an accurate alignment with each other and almost exactly parallel to each other. In the case when ring-like members are provided around the first and second dies or when teeth are formed at sides of each first and second die element, formation of local deformations at gaps between two adjacent first die elements and between two adjacent second die elements is suppressed.
