PROBLEM TO BE SOLVED: To provide a fuel injection device with improved positioning property, assembly property, and stiffness. SOLUTION: The fuel injection device 1 has components including an air-fuel mixture injection part 3, a fuel supply part 4, a fuel injection device holder 5, an inserting piece 6, a fuel inlet part 7, and an air inlet part 8. The fuel injection device holder 5 has an air-fuel mixture chamber 5a disposed in the fuel injection device holder 5 so as to mix the supplied fuel with the supplied air to generate the air-fuel mixture, a mixing part 51 disposed at one end part of the fuel injection device holder 5, and a connection part 5b disposed at the other end thereof. The fuel injection device holder 5 has an air supply passage 5c guiding the air introduced from the air inlet part 8 to the air-fuel mixture chamber 5a and extended between the air-fuel mixture chamber 5a and the connection part 5b. The air supply part 4 is coaxially integrated with the air-fuel mixture injection part 3 through the fuel injection device holder 5. COPYRIGHT: (C)2007,JPO&INPIT
