To provide a saddle type resin fuel tank which shortens a molding cycle time.SOLUTION: There is provided a saddle type resin fuel tank 1 that stores a fuel 43 supplied to an internal combustion engine mounted on a vehicle in a chamber having a saddle-shaped part 2 between a first chamber 3 and a second chamber 4, in which an arc-shaped part 16 in a deeply throttled region 15 of the saddle-shaped part 2 has a wavy-shaped part 20 in a cross section. A film thickness in a wavy-shaped part 20 of the saddle-shaped part 2 is formed so that a trough part 22 of the wavy-shaped part 20 is thinner than a mountain part 21 of the wavy-shaped part 2, and a film thickness of the mountain part 21 is the same as a film thickness in a portion other than the deeply throttled region 15.SELECTED DRAWING: Figure 2
【課題】成形サイクル時間を短縮する鞍型の樹脂製の燃料タンクを提供する。【解決手段】車両に搭載された内燃機関に供給する燃料43を、第1室3および第2室4の間に鞍状部2を有する室内に貯留する鞍型の樹脂製燃料タンク1であって、鞍状部2の深く絞られた領域15の弧状部16には、断面において波形状部20を有する。鞍状部2の波形状部20における膜厚は、波形状部20の谷部22が波形状部2の山部21に比べて薄く形成され、山部21の膜厚は、深く絞られた領域15以外の部分の膜厚と同じである。【選択図】図2
