Claims (2)
- 排気系路の末端に備えられて排気ガスを車外へ放出するテールパイプの水侵入防止構造であって、前記テールパイプに湾曲形状を付し且つその湾曲部位の曲がり方向外側の内周面に該内周面から排気ガスの流れ方向下流側に向け徐々に離間するように隔壁を設け、該隔壁と前記湾曲部位の曲がり方向外側の内周面との間に袋小路部を画成し、袋小路部の画成位置における隔壁が無い状態での流路断面積が湾曲部位の上流側の流路断面積よりも大きくなるように該湾曲部位の曲がり方向外側を膨出させたことを特徴とするテールパイプの水侵入防止構造。
- 隔壁により狭められる流路断面積をテールパイプの出口の開口断面積以上に確保したことを特徴とする請求項1に記載のテールパイプの水侵入防止構造。
