The invention relates to a locking device (SV) for an electric motor drive unit (EM-AE), wherein the locking device (SV) has a locking mechanism for locking a lockable shaft (W) of the electric motor drive unit (EM-AE) and an electric drive (EA) for actuating the locking mechanism, said drive being received by a housing (SV-G) of the locking device (SV) together with the locking mechanism. The locking mechanism has a first form-fitting element (4) with an inner toothing (IV) and a second shaft-side form-fitting element (6) with an outer toothing (AV) against which the first form-fitting element (4) can be actuated in a form-fitting manner in an axial stroke movement (X - X) along the shaft (W). A tapered section (7) which has a centering effect is molded on the end face of the shaft-side fom-fitting element (6) so as to face the first form-fitting element (4), the inner toothing (IV) striking said tapered section in order to align the two form-fitting elements (4, 6) relative to each other. The invention additionally relates to an electric motor drive unit (EM-AE), in particular for driving a vehicle comprising such a locking device (SV), and to a vehicle comprising such an electric motor drive unit (EM-AE).
