A windshield wiper device (), particularly for a motor vehicle, is proposed. This windshield wiper device comprises a wiper bearing () supporting a wiper shaft (), which has an undercut () in which a securing device () for axially fixing the wiper shaft () in the wiper bearing () is arranged. The securing device () can be displaced by the effects of a defined axial force component (F) on the wiper shaft (), whereby the wiper shaft () can be displaced in relationship to the wiper bearing (). According to the invention, the securing device () comprises a bushing section () with an indentation (), which engages in the undercut () of the wiper shaft ().

Windscreen wiping device, particularly for a motor vehicle

The invention starts with a fastening of a wiper system () to a vehicle body () by means of a rubber elastic fastening element (), which sits on the circumference in a receptacle opening () of the wiper system () or the vehicle body () and sits with a passage opening () on a pin () of the respective other part, whereby the connection between the wiper system () and the vehicle body () is detachable via a defined axial force () in the direction of the interior of the vehicle body (). It is proposed that a defined frictional force between the inner and/or outer circumferential surface () of the fastening element () and the adjacent component () is generated by an initial axial stress of the fastening element ().
