The drive shaft (1) carries drive members (21). At least some members are combined into groups, in which they are joined to each other by thin-wall, elastic expanded sleeves (22). The members are pref. integral with the sleeves. The shaft can be hollow and plastically expanded at the sleeve locations. Alternatively, the drive and sleeves can be shrunk onto it. The drive members, partic. where symmetrical ones, can have axial recesses (27) to form narrower radial ribs (24) between hubs and outside portions.
