Abstract
A miniaturized window wiper includes a mounting hub having a concealed mounting boss therein, the hub being pivotally connected to a wiper arm which further mounts and shrouds a wiper blade holder, the wiper arm being subjected to tension by a torsion spring in order to bias a wiper blade against a window. A motor drive system for imparting oscillating motion to the wiper is also disclosed.
