A drive mechanism for at least two windshield wipers of a vehicle, in particular of an automotive vehicle, with a driving motor (1) which includes a gear unit accommodated in a gear casing (2) which is closed by means of a cap and where, on the end of an output shaft (3) protruding from the gear casing (2), a motor crank (4) is fastened in a torsion-resisting manner for driving the wiper shafts (8) of the at least two wiper bearings (5, 11) via rods, is to be improved so that, on the one hand, it is easily adaptable to the space or installation conditions prevailing on the vehicle while, on the other hand, due to a reduced number of components, it can be manufactured at lower cost as compared to known drive mechanisms. This is achieved in that the one wiper bearing (5) is an integral part of the gear casing (2) or of the cap thereof and in that at least one further wiper bearing (11) is fastened on a carrier (12) of selectable length which, on its part, is fastened on the gear casing (2) or on the cap thereof.
