ABSTRACT:
A vacuum pump has a pump case having a gas suction port at an upper part of the pump case and a gas exhaust port at a lower part of the pump case. A stator column extends from a base of the pump case and has an outer circumferential surface. A rotor shaft is rotatably supported in the pump case by the stator column. A spacer is removably integrally connected to the outer circumferential surface of the stator column. The spacer has an outer circumferential surface spaced apart from an inner circumferential surface of the rotor and a through-hole extending form the outer circumferential surface to an inner circumferential surface thereof. A connecting member extends through the through-hole of the spacer and contacts the outer circumferential surface of the stator column to thereby removably integrally connect the spacer to the outer circumferential surface of the stator column.
