The invention relates to a wiper device (10) for motor vehicle windows (20) comprising a wiper arm (12) which can move between return positions and which is loaded toward the window. A longitudinally extended wiper blade (16), which can pivot around an axis (32) that points in a direction of wiping, is coupled to the free end of said wiper arm and can be moved, in a manner that is transversal to the direction of wiping, together with the wiper arm (12) out of its operational position and into a mounting position. The wiper device has two bearing journals (72). Said bearing journals belong to the pivotal joint, project from the longitudinal sides of the wiper blade (16), are aligned with one another, have non-circular cross-sections, and are guided in recesses (54) of the wiper arm (12) which are open at the edges. In addition, the wiper device is provided with means for limiting the pivotal movement (double arrow 34). It is possible to universally use means for limiting the pivotal movement if the wiper blade (16) is provided with a tongue-like projection (78) which extends at least approximately in the direction of pivot (double arrow 34) and which can be elastically guided outward. A stop shoulder (84) is placed on the free end of said projection and, when the wiper blade is mounted, engages behind a counter shoulder (94), which is provided on the wiper arm, in such a manner that the stop shoulder (84) and counter shoulder (94) form the limiting means.
