摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve for reducing the aging effect of the atomizing property of fuel when injected from a nozzle hole.
SOLUTION: A relationship between an inner diameter A of a suck part 30 and a distance B from a center axis c of the suck part 30 to the nozzle hole 31 is set to be 1≤A/2B≤20. Thus, fuel flowing from the suck part 30 into the nozzle hole 31 is injected via the nozzle hole 31 without being separated from the wall face of a valve body 21 forming the nozzle hole 31. The deposition of foreign matters on the wall face forming the nozzle hole 31 is therefore prevented, or even when deposited on the wall face, the foreign matters are removed therefrom by the fuel flowing in the nozzle hole 31. As a result, with the repeated injection of the fuel, there is no change in the injecting property of the fuel injected from the nozzle hole 31 due to the foreign matters deposited on the wall face. This reduces the aging effect of the atomizing property of the fuel when injected.

SOLUTION: The resin combustion gas seal 22 to which an outer diameter correction method is applied is installed in an installation groove 17 having a tapered face 20 of which diameter is enlarged toward an injector body side (right side in the figure) to seal an annular clearance between an injector mounting hole and the injector 13. At the time of the outer diameter correction, a plurality of segments 24 of the outer diameter correction tool 23 are assembled to form the outer diameter correction tool on a side closer to the injector body than the combustion gas seal 22 with a state of surrounding the injector 3. The outer diameter correction tool 23 is moved on a tip side of the injector so that the outer diameter correction tool 23 is away from the injector body. By the movement, an outer diameter of the combustion gas seal 22 is corrected that was enlarged at the time of installation thereof into the installation groove 17.
