PROBLEM TO BE SOLVED: To prevent the occurrence of a start failure of an engine by surely preventing a backflow of an exhaust gas by a simple constitution even if there is a wind which progresses ahead from a vehicle rear side.SOLUTION: A rectangular opening 1b is formed at a rear bumper 1, a square cylindrical base body 2 is horizontally arranged in front of the opening 1b, a flange part 2a which is integrally formed at a rear end part of the base body 2 is arranged so as to be superimposed on a peripheral edge of the opening 1b of the rear bumper 1, and an exhaust pipe 3 is arranged inside an insertion part 2b formed at an upper front end part of the base body 2 in a state that its rear end part is inserted therein. By this constitution, even if a wind progressing ahead from a vehicle rear side blows, an exhaust gas from the exhaust pipe 3 can be made to flow frontward in the base body 2 at a stop of an engine, a backflow of the exhaust gas to the exhaust pipe 3 can be surely prevented, and the filling of the exhaust gas to an engine intake system can be prevented.SELECTED DRAWING: Figure 2

    【課題】車両後方から前方に向かう風があっても、簡単な構成により排気ガスの逆流を確実に防止して、エンジンの始動不良の発生を未然に防止できるようにする。【解決手段】リアバンパ1に矩形状の開口1bを形成し、四角筒状の基体2を開口1bの前方に水平に配設し、基体2の後端部に一体形成されたフランジ部2aをリアバンパ1の開口1bの周縁に重合して配設し、基体2の上前端部に形成された挿入部2bの内側に排気管3の後端部を挿入した状態で配置する。これにより、車両後方から前方に向かう風が吹いていても、エンジン停止時に排気管3からの排気ガスが基体2内部を前方に流すことができ、排気ガスの排気管3への逆流を確実に防止してエンジンの吸気系への排気ガスの充満を防止することができる。【選択図】図2
