Abstract
A wiper apparatus for a vehicle windshield having a linkage pivotably attached to a main driving lever. Linkage is also coupled to a motor to rotate main lever for rotating a main shaft limit positions for selecting resting place of wiper blade. An eccentric cam is rotatably mounted to the main shaft with an intermediate member rotatable relative to the cam and attached to the linkage. A driving mechanism rotates the cam to adjust the position of the linkage relative to the driving lever which in turn determines the upper and lower position of wiper blade.
