The present invention relates to a dual fuel injector of a dual fuel vehicle, in a vehicle that uses gasoline and other fuels, such as LPG or SNG, etc., the injector 10 for injecting gasoline from the engine of the vehicle is Maintaining it as it is, and spraying LPG or SNG in a predetermined distance below the injection port 55 is formed on the side so that interference does not occur due to mutual installation with the gasoline injector 10 and the gasoline injector 10 and By providing a dual fuel injector of a dual fuel vehicle that is installed to face each other with the injection holes 14 and 55 as a starting point, it is possible to produce a dual fuel vehicle that can selectively use fuel such as gasoline, LPG, and SNG. There is an effect that can be produced while maintaining the basic design to the maximum.
