ることを特徴とする高圧燃料噴射管の接続溝 □造。[Scope of Claim for Utility Model Registration] For assembly, a hole 2 is provided through the shaft core, and a part of the hakama wall 4 near the rear end that is connected to the front brim-shaped locking wall 3 and connected to the rear thereof. The supporting rib washer 1 whose inner peripheral surface has a rearward opening with a gentle slope 4' is assembled into a connecting head in which the hole 2 and the locking wall 3 are integrally expanded at the end of the pipe 5. A bulging wall portion 9 is constructed so as to be press-fitted in the state of abutting and engaging with the neck and lower jaw portion of the portion 6, and the diameter of the gently sloped portion 4′ is slightly enlarged toward the side of the pipe 5 located near the gently sloped surface. The mating nozzle holder 8 is tightened by the nut 7, which is assembled at the back in a hot state.
As it is screwed and tightened, the bottom wall on the nut side presses against the locking wall 3, and the pressing surface 6' of the connecting head 6 is strongly pressed against the pressure-receiving opening surface 8'. A connecting groove for a high-pressure fuel injection pipe characterized by a structure.
