Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To hold gas tightness of a tip of a fuel injection valve with a throttle body and gas tightness of a rear end of the fuel injection valve with a fuel feed tube, and improve layout performance for assembling the fuel feed tube with the throttle body.
SOLUTION: A first seal ring 4 is disposed on the tip JA of the fuel injection valve J, and outer diameter parts 4A and 4B of the first seal ring 4 are supported in a compressed state by a first support shaft part 5 and a first large diameter support hole 14. The first seal ring 4 is disposed to face a first large diameter locking step part 8 and a third locking step part 16. A second seal ring 9 is disposed on the rear end JB of the fuel injection valve J, and outer diameter parts 9A and 9B of the second seal ring 9 are supported in a compressed state by a second support shaft part 10 and a second large diameter support hole 22. The second seal ring 9 is disposed to face a second large diameter locking step part 13 and a fourth locking step part 24. A fuel feed tube 20 provided with the second large diameter support hole 22, the fourth locking step part 24, and a fuel feed passage 21 is engaged with the throttle body 1 through a screw 66 to be fixed.
