An air curtain for cars is provided to settle inconvenience of being exposed to rain while getting into or out of a car when it rains, to prevent the inside of the car from getting wet by rainwater, to provide a pleasant driving environment, and to improve the durability of the car, by applying Bernoulli′s theorem, which means that if compressed air of a wide space is spouted to a narrow passage, the pressure decreases and the speed greatly increases, by strongly spouting air that is sufficiently compressed, so a strong shower will be blocked in an air spouting direction for two to three minutes when the driver is getting into or out of the car, and thereby unfolding an air curtain over the head of the driver. |
