摘要
The invention relates to an electric motor-driven motor-vehicle vacuum pump (1), having a drive shaft (3) which has, in particular, two bearings and extends with a shaft stub (5; 35; 45) in a rotor (8) which is connected fixedly to the shaft stub so as to rotate with it. In the rotor, the shaft stub has a centring region (26, 36; 46) which serves to centre the rotor, without guiding the rotor in the axial direction.
