PURPOSE: An air curtain of a window for a door in a vehicle is provided to keep the vehicle room clean, and to improve reliability by restricting rainwater or dust from being infiltrated into the vehicle room. CONSTITUTION: An air curtain of a window for a door in a vehicle is composed of plural pressure detecting sensors installed between a roof panel and a head lining to detect pressure of rainwater; window position sensors(30,31) installed in the lower part of the door window to detect the position of the window glass; and a control unit(32) receiving signals from the pressure detecting sensors and the window position sensors, and injecting air by operating a compressor(26). Comfortableness is improved by shutting off rainwater from the window of the vehicle.
