Abstract
A shaft, in particular a drive shaft, for transferring torques, includes a basic member made of an elastic first material, and connecting pieces shaped at their ends for being received by the basic member and prevented by positive engagement from rotating and displacing axially relative to the basic member. The connecting pieces are made of a second material which is inelastic or less-elastic than the first material or. The first and second materials are plastics which are crosslinked with one another at interfaces of the basic member and the connecting parts. The shaft is reliably functional while having a compact design.
