<P>PROBLEM TO BE SOLVED: To prevent excessive forcing load from being applied to a fuel injection valve 10 after fuel pressure increases. <P>SOLUTION: The front end side of a fuel injection valve 10 is inserted into a mounting hole 9 in a cylinder head 1, and the base end side of the fuel injection valve 10 is inserted into a fuel outlet pipe 13 of a fuel distribution tube 12 through an O-ring 17. A spring member 18 which is placed between the fuel outlet pipe 13 and the fuel injection valve 10 and presses the fuel injection valve 10 to the cylinder head 1 side is provided. Moreover, responding to fuel pressure inside the fuel outlet pipe 13 which acts on the O-ring 17, a pressure corresponding movement member 19 which presses the fuel injection valve 10 to the cylinder head 1 side by acting on the fuel injection valve 10 at the time of increase of fuel pressure is provided. At the same time, the fuel pressure corresponding movement member 19 acts on the fuel outlet pipe 13 side of the spring member 18 so that the spring 18 may be separated from the fuel outlet pipe 13. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
