The nozzle (3) can be moved into a working position (3') by a hoist cylinder (4) and a piston rod (5). The nozzle (3) is guided through an opening (2) in the car body (1) which is covered (6) as long as the washer unit is not used. A locking element (9), joined to the hoist cylinder (4) engages with a recess (10) in the car body in order to reduce the tolerance and to protect the nozzle unit (3,3') during the positioning process.
