<p>The invention relates to a wiper arm with a hinged wiper blade and a fixing part (10) for fixing to a drive shaft (12). This is done by inserting said shaft through a widening recess (38) of the fixing part (10). A screw nut (44) fastens the fixing part (10) and the drive shaft (12) against a locating surface (30) by means of a clamping part (40, 50) that matches the recess (38). According to the invention, the contact surface (66) between the clamping part (40, 50) and the fixing part (10) form part of the surface of a sphere and the locating surface (30) forms part of a surface area of a cylinder, the axis of the cylinder (32) extending through the center point of the sphere (36) and parallel to the longitudinal direction (34) of the wiper blade.</p> |
