The invention relates to a windshield wiper device for a vehicle, in particular a motor vehicle, having a fastening element fastened to a drive shaft. The windshield wiper device comprises a wiper blade having an elongate upper part, which is at least partially flexible, an elongated lower part, which is at least partially flexible, and a plurality of connecting elements for connecting the upper part and the lower part. Along a longitudinal extension of the wiper blade, the connecting elements are spaced apart from one another, wherein the connecting elements are designed to allow a movement of the upper part and the lower part relative to one another, by means of a movement component, along a longitudinal extension of the wiper blade. The windshield wiper device further comprises a fastening part on the wiper blade side, wherein the fastening part on the wiper blade side comprises a clamping device such that the fastening part on the wiper blade side can be adjusted to the dimension of at least part of the drive shaft.
