This device reduces the load on the axis of the gear reducer when moving the blades.

On one side of the lever hub is mounted, on the other side - blade. Hub and lever swivel serve to provide the necessary contact pressure of the blade to the windshield. There is a special sleeve to fasten the lever on the axis of the gear reducer. The sleeve has an outer conical finely grooved thread, which presses on the gear reducer axle. In the hub bore there are cut slots of the same type. The lever is fixed on the axle with a nut.
