A windshield wiper device (10), particularly for a motor vehicle, is proposed. This windshield wiper device comprises a wiper bearing (14) supporting a wiper shaft (16), which has an undercut (48) in which a securing device (40) for axially fixing the wiper shaft (16) in the wiper bearing (14) is arranged. The securing device (40) can be displaced by the effects of a defined axial force component (F) on the wiper shaft (16), whereby the wiper shaft (16) can be displaced in relationship to the wiper bearing (14). According to the invention, the securing device (40) comprises a bushing section (42) with an indentation (50), which engages in the undercut (48) of the wiper shaft (16).
