To provide a corrugate mounting structure capable of preventing water immersion from a gap between a corrugate tube and a grommet in a connected portion to the inside and capable of easily recovering a water cutoff performance even if the water cutoff performance is reduced between the corrugate tube and the grommet, and an annular member.SOLUTION: A corrugate mounting structure comprises: a corrugate tube 10 in which small diameter parts 11 and large diameter parts 12 are formed alternately in a length direction X; a grommet 20 of which the end is externally fitted to an end of the corrugate tube 10; and an annular member 30 mounted to a connected portion 60 where the corrugate tube 10 and the grommet 20 are connected. The annular member 30 is formed in a cylindrical shape having elasticity and includes: a corrugate external fitting part 31 externally fitted to the corrugate tube 10 in the connected portion 60; a grommet external fitting part 32 externally fitted to the grommet 20 in the connected portion 60; and an annular connection part 33 integrally connecting the corrugate external fitting part 31 and the grommet external fitting part 32.SELECTED DRAWING: Figure 1 【課題】連結部分におけるコルゲートチューブとグロメットとの間からの内部への浸水を防止することができ、かつ、コルゲートチューブとグロメットとの間における止水性能が低下しても容易に回復することができるコルゲート装着構造、及び環状部材を提供すること【解決手段】小径部１１と大径部１２とが長手方向Ｘに沿って交互に形成されたコルゲートチューブ１０と、端部が、コルゲートチューブ１０の端部に外嵌するグロメット２０と、コルゲートチューブ１０とグロメット２０とが連結する連結部分６０に装着される環状部材３０とが備えられ、環状部材３０は、弾性を有する筒状であるとともに、連結部分６０におけるコルゲートチューブ１０に外嵌するコルゲート外嵌部３１と、連結部分６０におけるグロメット２０に外嵌するグロメット外嵌部３２と、コルゲート外嵌部３１とグロメット外嵌部３２とを一体に繋ぐ環状繋部３３とが備えられている。【選択図】図１
