PROBLEM TO BE SOLVED: To provide a flexible conduit for an exhaust pipe of an automobile for improving durability of a bellows member.SOLUTION: A flexible conduit for an exhaust pipe provides a flexible conduit for an exhaust pipe of an automobile, and its bellows member (10) has a salient (12), a central part (C) and both ends (U). The salient (12) has a uniform outer diameter, the central part (C) has the maximum concave inner diameter (D3) larger than the minimum concave inner diameter (D1), an outer cover member (30) is formed by an outer net part having a net-like structure, the concave part inner diameter at the central part of the bellows member is larger than the concave inner diameters at both ends so as to prevent interference between an interlock member (20) and the bellows member.
【課題】ベローズ部材の耐久性を改善する自動車の排気管用可撓性導管を提供する。【解決手段】排気管用可撓性導管は、自動車の排気管用可撓性導管を提供し、そのベローズ部材(10)が凸部(12)、中央部(C)及び両端部(U)を有し、凸部(12)が均一な外径を有し、中央部(C)が両端部(U)の最小凹部内径(D1)よりも大きい最大凹部内径(D3)を有するようになっており、外側カバー部材(30)は網状構造を持つ外側網部で形成されており、インターロック部材(20)及びベローズ部材の間の干渉を防止するように、ベローズ部材の中央部の凹部内径は両端の凹部内径よりも大きくなっている。【選択図】図1
