ABSTRACT:
In a type disc for typewriters or the like, for locking the hub (1) of the type disc on a drive shaft there is a plurality of catch noses (7) arranged at the ends of cantilever arms (8, 11), of which the rear sides (9), as seen in the axial direction of the type disc, are at a distance from the inner wall (10) of a central hole (2) for receiving the drive shaft. The gaps which the maintained distance brings about allow an economical production of the type disc.
