Date Jan. 19, 1995A driving crank for a windshield wiper system, wherein the crank lever is made of deep-drawn sheet metal. The crank lever has a rear part and a circumferential edge beaded towards one side of the rear part. At one end, the crank lever has an opening with an edge beaded towards the same side so as to form an inner cone. To prevent the inner cone from expanding and to reliably transmit high torques between the driving crank and the shaft to be secured in the opening, and vice-versa, the inner cone is expanded from the rear part.
