Abstract
A drive unit, in which an unattached shaft end of a drive shaft abuts axially against an abutment surface of a housing part. The abutment surface is crown-faced and with respect to the abutting, unsupported and unattached (i.e., free) shaft end and thereby prevents the drive shaft from deflecting eccentrically from radial adjusting forces. Given an eccentric abutment, the abutment surface leads the drive shaft back to its centrical axial position.
