The invention relates to a device for mounting a windshield wiper on a vehicle body. Said mounting device comprises an elongated support with a pre-assembled wiper motor, a transmission, a driving crank and a transmission rod assembly that is linked with said driving crank and with at least the drive shaft for a wiper arm by means of a pivoted lever. The support structure is linked with the vehicle body in three mounting points. It is the aim of the invention to design a mounting device that requires only little assembly space for mounting the equipped support structure on the vehicle body and that facilitates the assembly. To this end, two of the mounting points (P1 and P2) that are used to establish a firm connection with the vehicle body are located along the longitudinal axis of the support structure (1) and are spaced apart from one another. The third mounting point (P3) is located at a distance from the connecting line between said mounting points (P1, P2) and is configured as a connector element (10) of a vibration-free and noise-reduced connector for a counter piece (11) to be firmly mounted on the vehicle body. The direction of connection is substantially transversal to the rotational axis of the drive crank (6) that drives the drive rod assembly (7).
