PROBLEM TO BE SOLVED: To provide a water intrusion prevention structure of a tail pipe capable of positively preventing washing water from intruding into a deep position of the tail pipe when a vehicle body is washed with high pressure.SOLUTION: This invention relates to a water intrusion prevention structure of a tail pipe 1 arranged at a terminal end of an exhaust gas system passage to discharge exhaust gas 3 out of a vehicle, the tail pipe 1 is applied with a curved shape and a partition wall 5 is arranged at an inner peripheral surface of the curved location 1a in an outside part of its bending direction in such a way that the partition wall is gradually spaced apart from the inner peripheral surface toward a down-stream side in a flowing direction of the exhaust gas 3, and a dead end part 6 is defined between the partition wall 5 and the inner peripheral surface of the bent part 1a outside in a bending direction.SELECTED DRAWING: Figure 1

    【課題】車体の高圧洗浄時に洗浄水がテールパイプの奥まった位置まで侵入してしまうことを確実に阻止し得るテールパイプの水侵入防止構造を提供する。【解決手段】排気系路の末端に備えられて排気ガス3を車外へ放出するテールパイプ1の水侵入防止構造に関し、前記テールパイプ1に湾曲形状を付し且つその湾曲部位1aの曲がり方向外側の内周面に該内周面から排気ガス3の流れ方向下流側に向け徐々に離間するように隔壁5を設け、該隔壁5と前記湾曲部位1aの曲がり方向外側の内周面との間に袋小路部6を画成する。【選択図】図1
