The invention relates to a rear windscreen wiper comprising an electric drive assembly, in particular for a motor vehicle. Said wiper comprises an armature shaft (10) and an armature core (15), the armature shaft (10) being mounted by means of at least one anti-friction bearing (11) and also comprises a screw (12) for driving a drive mechanism. The armature shaft (10) is produced from bar stock that has a nominal diameter (13), which remains uniform over the length of the armature shaft (10), of between 5 mm and 7 mm, preferably 5.5 mm and 6.5 mm. To produce a frictional fit between the screw (12) and/or the anti-friction bearing (11) and/or the armature core (15), the assembly has at least one tumble finished structure (14). |
