<p>An electric drive unit for windshield washers of a motor vehicle, including a drive motor having an armature accommodated in a substantially cup-shaped pole housing, a substantially cup-shaped gearbox, secured by its face end to the pole housing, for receiving at least one transmission gear wheel that meshes with a worm connected to an armature shaft of the armature. The armature shaft has a mushroom-shaped stop face on its face end, against which a spring for generating a defined initial stress comes to rest. The spring is a curved bendable spring, which has a substantially V-shaped profile, with a tensioning plate secured in the gearbox and with a leg that yields in the axial direction of the armature shaft, which in the installed state of rest, the spring exerts a spring force, on the mushroom-shaped face of the armature shaft.</p> |
