Claims

[Scope of utility model registration request]

It is composed of a hollow cylindrical main body and a flange, and a vibration damper made of an elastic material such as rubber and having a hole for fitting an injector is inserted into the main body. A heat insulator made of a heat insulating material such as Bakelite, in which a thin groove is perforated in the outer peripheral surface of the main body part in the circumferential direction, and a plurality of protrusions extending in the radial direction are provided in the lower surface of the flange part. and an O-ring installed in the narrow groove, and the O-ring is installed in the injector mounting part of the cylinder head or intake manifold while maintaining a slight gap between the mounting hole of the injector mounting part and the inner wall surface thereof. An injector mounting device for a fuel-injected internal combustion engine, characterized in that the body portion is press-fitted by pressing an O-ring, and the injector mounting portion is mounted with only the protruding portion in contact with the upper surface of the injector mounting portion.
