A wiper apparatus (10) for motor vehicle windows (20) is proposed, having a wiper arm (12) that can be moved between reversal positions, is loaded toward the window (20), and whose free end is connected to an elongated wiper blade (16), which can pivot around an axis (32) pointing in the wiping direction, and together with the wiper arm (12), can be moved lateral to the wiping direction, from its operating position into an installation position. The wiper apparatus has two bearing pins (72), which are part of the pivot hinge, protrude from the longitudinal sides of the wiper blade (16), are aligned with each other, are noncircular in cross section, and are guided in recesses (54) of the wiper-arm (12) that are open at the edge, and is provided with means for limiting the pivoting motion (double arrow 34). A universal use of means for limiting the pivoting motion is achieved if the wiper blade (16) is provided with an elastically deflectable, tab-like protrusion (78), which extends at least approximately in the pivot direction (double arrow 34) and has a stop shoulder (84) disposed at its free end which, when the wiper blade is installed, engages behind a counterpart shoulder (94) on the wiper arm in such a way that the stop shoulder (84) and the counterpart shoulder (94) constitute the limitation means.
