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.

A printwheel for typewriters or the like having a hub made of resiliently deformable synthetic material and defining a central hole having an inner wall for receiving a drive shaft for providing rotation of said printwheel;
- said hub carrying a plurality of flexible webs;
- said plurality of flexible webs including lugs for engaging and end of said drive shaft having an annular receiving groove defined therein;
- each of said webs having a rear portion being positioned at a distance from said inner wall of said central hole as seen in an axial direction of said printwheel;
- characterized in that said webs are formed from cantilever arms having arcuate portions partially surrounding said drive shaft in an arch-wise manner when said drive shaft is received in said central hole;
- and that each of said arcuate portions has opposed ends, one of said ends being attachable to the hub and the other of said ends being provided with one of said lugs for engaging said drive shaft.
