A motor vehicle vacuum pump includes a pump rotor, a coupling element, and a clutch arrangement. The clutch arrangement locks or releases the coupling element to/from the pump rotor so that the coupling element rotates together with or is released from the pump rotor. The clutch arrangement comprises a bolt holder connected to the pump rotor or to the coupling element to rotate therewith, an axially displaceable guide body, and a catch body connected to the coupling element or to the pump rotor to rotate therewith. The bolt holder comprises a bolt guide and a bolt body displaceable therein. The guide body is assigned to the bolt holder and comprises a guiding surface inclined with respect to an axial plane. The bolt body is forced radially into a locking position via the guiding surface. The catch body has a catch depression wherewith the bolt body engages in the locking position.
