Abstract

　車載エンジンの排気管。外管１１０内に挿入された内管１３１が、その外側端部１３２Ｃにおいて、外管１１０の内周面に第１の位置で接触するとともに、外管１１０が内管１３１に対し第１の位置と異なる第２の位置で接触し、内管１３１と外管１１０との間に膨張室１３５が形成される。内管１３１は、内管１３１の内部と膨張室１３５とを連通する複数の連通孔を有し、それにより消音器が構成される。外管１１０内には膨張室１３５に隣接して排気浄化触媒２１が設けられる。そして、外管１１０の内周面には、内管１３１の外側端部１３２Ｃと排気浄化触媒２１との間に凝縮水の流れを止める堰１１６が設けられる。したがって、排気管１０１において、排気が冷却されることにより生じる凝縮水が排気浄化触媒に接触することに起因して排気浄化触媒の浄化機能が低下することを抑制することができる。
