PROBLEM TO BE SOLVED: To provide a fuel injection device which extremely reduces transmission of solid transmission sound from a fuel injection valve to a cylinder head.SOLUTION: A fuel injection device includes a fuel injection valve 1, a reception hole 9 for the fuel injection valve 1 on a cylinder head 17 and a fuel distribution pipe path 4 provided with a connection pipe piece 6, the fuel injection valve 1 being inserted to the connection pipe piece so as to partially overlap the connection pipe piece. Therein, a coupling body 18 is disposed, the coupling body is arranged so as to retain the fuel injection valve 1 in the coupling body, the fuel injection valve 1 is inserted to the receptor hole 9 of the cylinder head 17 without coming into contact with all surfaces or walls which are not extended in the axial direction with respect to the fuel injection valve 1 of the reception hole 9 of the cylinder head 17, the coupling body 18 is formed in a pipe shape, the connection pipe piece 6 has a collar 15 partially extended in a ring shape on the downstream side edge part, the collar corresponds to the coupling body so as to fix the coupling body 18 and the coupling body 18 is engaged with a housing shoulder part 20 of the fuel injection valve 1 from below. |
