A branch connector in a fuel pressure accumulating container is joined with a through hole formed on a peripheral wall of the pressure accumulating container. The branch connector is inserted deeply into the through hole until the distal end of the branch connector is projected from the inner peripheral wall surface of the pressure accumulating container. Thus, the internal pressure fatigue strength is improved by lowering the maximum stress value generated at the internal peripheral edge at the lower end of the branch connector.
