ジ７との間に形成される隙間を示す。 The engine member 1 consists of the cylinder head of the engine or an intake manifold extending from the engine cylinder head, and the nozzle 3 is inserted into the O-ring 14 on the outer periphery of the small diameter portion 13 on the tail end side. It was inserted into the hole 15 and opposed to the pipe 4, and was pressed against it by the aforementioned tightening. The bushes 12 are fitted into bush holes 16 pre-formed in the flange 7, and are positioned relative to each other at intermediate step portions 17. In the figure, reference numeral 18 indicates a gap formed between the member 1 and the flange 7 due to the protrusion of the respective end portions 6a, 12a.

得られる等の効果を有する。 In this way, according to the present invention, the fuel nozzle 3 is fitted into the insertion hole 8 of the front flange 7 of the holder 2.
The seal ring 6 projects from the front face of the flange 7 at its front end 6a, and a bushing 12 made of heat insulating material is attached to the flange 7, surrounding a thread 9 that fixes it to the engine member 1. The front end 12a is locked by the intermediate step 17.
The fuel nozzle 3 is brought into pressure contact with the engine member 1 through the seal ring 6 to complete the seal, and the front flange 7 is mounted with a gap 18 between it and the engine member 1, and the flange 7 and the flange 7 are attached to the holder 2.
Since heat from the engine member 1 side is not conducted through the thread 9 applied to the engine member 1, good heat insulation can be obtained.
