In the case of a windshield wiper drive having a swivelably mounted drive shaft, a drive rocker arm that is immovably attached thereto, a connecting lever which is attached to the drive rocker arm via a first joint, a support rocker arm which is connected to the connecting lever via a second joint and mounted via a joint, and a windshield wiper arm which is connected to the connecting lever, an object is to prevent distortion in the drive, while keeping production expenditures to a minimum. To accomplish this, one of the two joints of the connecting lever is swivelable in a plane that is defined by the axis of rotation of the accompanying rocker arm and by the corresponding joint, and the other joint is fixed in a plane that is defined by the axis of rotation of the accompanying rocker arm and by the joint.
