ABSTRACT:
In a windshield wiper system a washing liquid channel runs through a bore in the wiper shaft and extends through a bore in the cap of a wiper arm, so that in the operating position of the cap the nozzle is arranged on that side of the cap which is opposite a fastening member, so that, in comparison with prior constructions, good cleaning effect is achieved due to an enlarged spacing between nozzle and window pane to be cleaned. So that the protruding nozzle body does not impede swivelling of the cap, the bore in the cap is larger than the outer diameter of the nozzle body and the annular gap between the rim of the bore in the cap and the nozzle body may be closed by an additional cap.
