PURPOSE: An automatic snow removal device for a car window is provided to intermittently or continuously operate a wiper drive unit and a wiper by sensing snow on a vehicle glass. CONSTITUTION: An automatic snow removal device for a car window comprises a wiper drive unit (20), a wiper (21), a washer fluid drive unit (30), washer fluid (31), a snow sensor (40), a control unit (50), and a battery (10). The wiper drive unit and the wiper are powered to remove snow from a car glass when a car does not start. The washer fluid drive unit and the washer fluid are powered to remove foreign materials from the car glass. The snow sensor is installed on the inner surface of the car glass and senses the amount of snow on the car glass. The control unit receives the sensed signal from the snow sensor and powers either the wiper drive unit or the washer fluid drive unit. The battery supplies power to either the wiper drive unit or the washer fluid drive unit.
