The invention relates to a means for cleaning a blade of a window glass wiper of a vehicle. The means comprises at least one wiping edge (6) provided on the outer surface of the glass (2) within the area of motion of the wiper blade (6), whereby the blade (3) slides across the wiping edge when the wiper is on operation. The wiping edge (6) is formed by an edge of a groove provided on the surface of the glass (2). In order to reduce the striking forces acting on the drive mechanism of the wiper and to diminish wearing of the blade itself, the bottom of the groove (11) is provided with a ridge (5) extending longitudinally with respect to the groove essentially in the middle thereof. The upper edge of the ridge is rounded and has a lower position than the outer surface of the glass (2). |
