The present invention relates to a fuel mixing prevention device for a vehicle, which can prevent supply of a different kind of fuel into a diesel vehicle. According to the present invention, when a vehicle is being fueled and a fuel filling gun with a large radius is being inserted, a locking button is not pressed and a flapper is open by using difference of a radius between a fuel filling gun of gasoline and that of diesel, and when a fuel filling gun of gasoline with a small radius is being inserted, a locking button is pressed and a flapper is not open. By realizing a new form of a fuel mixing prevention device, the fuel mixing prevention device provided in the present invention is able to fundamentally prevent supply of an inappropriate fuel into a vehicle.

    본 발명은 디젤 차량에 타유종의 연료가 오주유되는 것을 막을 수 있는 차량의 혼유 방지 장치에 관한 것이다. 본 발명은 연료 주입 시 가솔린 주유건과 디젤 주유건의 직경 차이를 이용하여 직경이 큰 디젤 주유건을 삽입하는 경우 잠금단추가 눌리지 않으면서 플래퍼가 열리도록 하고, 직경이 작은 가솔린 주유건을 삽입하는 경우 잠금단추가 눌리면서 플래퍼가 열리지 않도록 하는 새로운 형태의 혼유 방지 장치를 구현함으로써, 차량에 맞지 않는 유종의 주유를 근본적으로 방지할 수 있는 차량의 혼유 방지 장치를 제공한다.
