Abstract:
Provided is an end seal structure of a fuel rail for a gasoline direct injection engine, the end seal structure being characterized in that: a collar is joined by brazing to an outer circumference of an end of a pipe of the rail body including a pipe; the end cap having a cap-nut shape and including a sealing projection on an surface thereof facing the opening at the end of the pipe of the rail body, is screwed and fixed to the collar; and the sealing projection of the end cap brings into pressure contact with the end of the opening of the rail body by an axial force created by tightening of the end cap having the cap-nut shape to seal the end of the opening of the rail body.
