る内燃機関の燃料噴射装置。 Upper and lower parts 2 apart in the axial direction of the outer circumferential wall of the fuel injection valve body
A fuel flow port to the inside of the fuel injection valve is opened at a location, and the fuel injection valve is housed in a holder that communicates with a fuel gear gallery, and a fuel gear and fuel flow are connected between the inner peripheral wall of the holder and the outer peripheral wall of the fuel injection valve body. In a fuel injection device for an internal combustion engine, in which a fuel passage is formed in communication with a fuel injector, a stepped portion is formed in the intermediate portion of the outer circumferential wall of the fuel injector main body, and the stepped portion is engaged with the stepped portion formed in the inner circumferential wall of the holder. A fuel injection device for an internal combustion engine, characterized in that a plate-shaped insulator is interposed between these locking steps, and a communicating groove is formed in the radial direction on the surface of the insulator.
