Abstract
The invention relates to an electric motor-driven motor-vehicle vacuum pump (), having a drive shaft () which has, in particular, two bearings and extends with a shaft stub () into a rotor () which is connected fixedly to the shaft stub so as to rotate with it. In the rotor, the shaft stub has a centring region () which serves to center the rotor, without guiding the rotor in the axial direction.
