To inhibit infiltration of water into an exhaust pipe and an increase in exhaust pressure by using a simple configuration.SOLUTION: An exhaust pipe structure 1 includes: a cylindrical exhaust pipe 2 having two pipes 3, 4 which are coupled to each other by fastening flanges 3f, 4f thereof to each other by bolts; and a blocking wall 6 provided integrally with a plate member 7 nipped between the flanges 3f, 4f. The exhaust pipe 2 is used for discharging exhaust gas of an engine mounted on a vehicle to outside of the vehicle. The blocking wall 6 is protruded from an inner wall surface 2c of the exhaust pipe 2 toward the inner side and downstream side.SELECTED DRAWING: Figure 3

    【課題】シンプルな構成で排気管への水の浸入と排気圧の増加とを抑える。【解決手段】排気管構造1は、互いのフランジ3f,4fをボルト締めされることで連結される二つのパイプ3,4を有する円筒状の排気管2と、フランジ3f,4fに挟持される板部材7と一体で設けられた遮壁6とを備えている。排気管2は、車両に搭載されたエンジンの排気を車両の外部に排出する。遮壁6は、排気管2の内壁面2cから内側かつ下流側へ向けて突設されている。【選択図】図3
