Patent ID: 6929288

Claim:
A connecting structure for a fuel pressure accumulating container having a curved peripheral wall with inner and outer peripheral surfaces, the inner peripheral surface defining an interior within the fuel pressure accumulating container, the connecting structure comprising: at least one cylindrical through hole formed through the peripheral wall and communicating with the interior; and a branch connector inserted into the through hole, the branch connector having a proximal end externally of the fuel pressure accumulating container, a distal end, a branch flow path extending linearly through the branch connector from the proximal end to the distal end, and a cylindrical outer surface engaging the peripheral wall at the through hole and extending to the distal end, portions of the branch connector in the through hole defining a substantially uniform radial thickness, the branch connector being inserted sufficiently deeply into the through hole so that the distal end thereof is projected from the inner peripheral surface of the peripheral wall of the container into the interior of the container by a length of projection that is not less than the radial thickness of the branch connector.
