Abstract
For miniature drives which are used in particular in car locks, the axial play of the motor spindle is prevented, or is at least greatly restricted, by the necessary axial stop and also the further motor stop being assigned to the housing cover of the housing. When the housing cover is placed onto the housing casing, said axial stops are inserted into corresponding guides in such a manner that said axial stops subsequently not only restrict the play of the motor spindle and ensure an always uniformly secure arrangement of the motor housing in the housing, but at the same time also make possible the substantially simpler production of the required bearing bore. Said bearing bore and the associated aperture are produced from the outer side of the housing casing during the injection molding.
