ABSTRACT:
The washer apparatus for washing the window of a motor vehicle comprises a wiper blade oscillating over the window sitting on a hollow shaft, which is provided with at least one nozzle directed at the window to be washed. A washer fluid feed occurs to the nozzle through a structural element in a shaft passage of the hollow shaft, whose one downstream end portion is rigidly attached with the hollow shaft. A particularly trouble-free and economical washer apparatus can be attained when the other upstream end portion of the structural element is held fixed behind an upstream opening of the shaft passage and the structural element is at least partially made from a pliable material.
