Windscreen wiper device, in particular for a vehicle

The windscreen wiper arrangement has at least one, especially electrically reversible, drive (12) with an armature shaft (16) carrying a worm that engages a worm wheel (28) with an output shaft (30). A blocking element (36) is provided that mechanically blocks the worm wheel against rotation when the armature shaft is stationary. The armature shaft can be displaced axially.
