ABSTRACT:
The invention refers to a wiper arm with a fixing part made from asheet metal, comprising a bore for the non-rotatable fixation on a wiper shaft and which is provided at least around the bore with an upper sheet metal section and a bottom sheet metal section being integrally connected and lying approximately in parallel to said upper sheet metal section. In order to provide the fixing part in the area of the bore with a high stability of form, a sheet metal section is supported against the flat side of the other sheet metal section around the bore at a distance from the outline of the fixing part which can be noticed when looked at in direction of the axis of the bore.
