The first flange (7) comprises a central portion (71), a generally annular peripheral portion (73) and at least one arm (75) which connect(s) the central portion (71) and the peripheral portion (73) to each other. The second flange (9) is homologous to the peripheral portion (73) of the first flange (7). In the assembled state, the wheel body (3) has a rim (121) which is formed together by the peripheral portion (73) of the first flange (7) and the second flange (9) and a hub which is formed by the central portion (71) of the first flange (7).
