<p>PURPOSE:To prevent the pressing seat face of a pressing head part from biting into the pipe outer face side opening end part of a pressure receiving seat face by forming the pipe outer face side opening end part of the pressure receiving seat face on the fuel rail side into an approximately circular-arc face. CONSTITUTION:A pressure receiving seat face 2 is formed into a rotated face rotated around the axis of a through hole, and a pressing head part 4 is formed into a rotated face with its contact line with the pressure receiving seat face 2 to be circular. Circular-arc faces 2-2 are formed at least on both longitudinal sides of the fuel rail outer face side opening end part of the pressure receiving seat face 2, and the pressing head part 4 is irregularly fitted at the pressure receiving seat face 2, thus connecting a branch connected body fixedly at the fuel rail. Accordingly, at the time of press-fitting the pressing head part 4 of the branch connecting body at the pressure receiving seat face 2, the pressing seat face 4-1 of the pressing head part 4 is prevented from biting into the outer face side edge part of the pressure receiving seat face 2, thereby preventing the generation of a gap between the pressing seat face 4-1 of the pressing head part 4 and the pressing receiving seat face 2.</p> |
