A vacuum pump comprises a cylindrical rotor; a cylindrical stator which discharges gas in cooperation with the rotor; and a tubular base to which the stator is fixed. The stator has no fitting structure with respect to the base and is fixed to the base in a concentric state. A pin hole is formed on the stator and the base respectively, and a positioning pin for achieving the concentric state is inserted into each pin hole. |
