Zusammenfassung: | To provide an exhaust structure which can prevent a sensor from being covered with water.SOLUTION: An exhaust structure 100 comprises an exhaust pipe 10 for introducing an exhaust gas from an internal combustion engine to a muffler, a partitioning member 30 placed in the exhaust pipe, and a sensor 20a having a detection part. The exhaust pipe 10 has a straight pipe 11, and a water sump part 12 connected to the straight pipe 11, and having an inside diameter larger than the straight pipe 11. The sensor 20a is attached to the straight pipe 11 so that the detection part is located in the straight pipe 11. The partitioning member 30 extends in an extension direction of the straight pipe 11 from the inside of the water sump part 12 so that the partitioning member 30 is interposed between an inner wall face of the straight pipe 11 below the detection part and the detection part.SELECTED DRAWING: Figure 2
【課題】センサが被水することを抑制可能な排気構造を提供する。【解決手段】排気構造100は、内燃機関からの排気ガスをマフラに導く排気管10と、排気管の内部に配置されている仕切り部材30と、検知部を有するセンサ20aとを備える。排気管10は、直管部11と、直管部11に接続されており、直管部11よりも内径が大きい水溜まり部12とを有している。センサ20aは、検知部が直管部11の内部に位置するように直管部11に取り付けられている。仕切り部材30は、検知部の下方にある直管部11の内壁面と検知部との間に仕切り部材30が介在されるように、水溜まり部12の内部から直管部11の延在方向に沿って延在している。【選択図】図2 |
