。[Scope of Claim for Utility Model Registration] A cylindrical casing is provided in the middle of the piping in a direction perpendicular to the cylindrical casing, and within this casing, a fuel injection valve with a fuel inlet opening on the side is installed on the tip side from the fuel inlet. and the distal side O placed on the proximal side, respectively.
In a fuel supply system for an internal combustion engine that is housed through a ring and a proximal O-ring, an enlarged diameter portion is formed in the fuel injector on the proximal side of the distal O-ring, and an enlarged diameter portion is formed on the distal side of the distal O-ring. At the same time, a diameter-reduced part is formed in the casing to sandwich the distal O-ring from above and below, and an enlarged-diameter part is formed in the fuel injection valve at the distal end of the proximal O-ring, and a diameter-enlarged part is formed in the fuel injection valve at the distal end of the proximal O-ring. 1. A fuel supply device for an internal combustion engine, characterized in that a holding member to be fixed is disposed on the base end side of a base O-ring so as to sandwich the base O-ring from above and below.
