PURPOSE: A wiper is operated automatically in a rainy condition, while enabling changing wiper speed by a driver in the automatic wiper driving mode. CONSTITUTION: A rain sensor wiper driving device is composed of an automatic mode switch(150) for setting an automatic mode of wiper operation. A rain sensor transmits signal when a raindrop is detected while driving. A speed varying switch(120) is provided to input wanted wiper speed. A controller(130) is installed to analyze signal from the rain sensor to operate the wiper according to a speed control line in an inner memory. When a speed varying switch signal is inputted, a control signal is outputted from the controller to change wiper speed.
