PROBLEM TO BE SOLVED: To enhance the effectiveness of the fall prevention of a flow passage forming member for forming a nozzle insertion passage.SOLUTION: A flow passage forming member 60 attached to a pipe opening end PT of a filler pipe forms an insertion flow passage part 12u of an oil feed nozzle by communicating with a fuel flow passage 11, flow passage inside/outside external peripheral walls 11i to 11o at the pipe opening end and a peripheral edge wall 11t of the pipe opening end are covered with an opening end engagement part 29 around the flow passage, and engaged with the filler pipe at the pipe opening end. By this constitution, the flow passage forming member which is attached to and engaged with the filler pipe is fastened to the filler pipe by a fastening part attached to the filler pipe in a state that a pipe external peripheral wall of the filler pipe is covered with an external peripheral coating part 21 which is continuously arranged toward a downstream side of the fuel flow passage from an opening end engagement part.SELECTED DRAWING: Figure 4
【課題】ノズル挿入通路を形成する流路形成部材の脱落防止の実効性を高める。【解決手段】フィラーパイプのパイプ開口端PTに装着される流路形成部材60は、給油ノズルの挿入流路部12uを燃料流路11に連通して形成し、開口端係合部29により、パイプ開口端における燃料流路の流路・内外周壁11i・11oとパイプ開口端の周縁壁11tを流路回りに覆われて、フィラーパイプとパイプ開口端において係合する。こうしてフィラーパイプに装着・係合された流路形成部材は、開口端係合部から燃料流路の下流側に掛けて連設された外周被覆部21でフィラーパイプのパイプ外周壁を覆った状態で、フィラーパイプに装着された締結部により、フィラーパイプに締結される。【選択図】図4
