Abstract

　本発明は、内視鏡の挿入部に設けられ、湾曲作動される湾曲部に関し、円滑に湾曲作動可能であり容易に製造することが可能な内視鏡湾曲部を提供することを目的とする。 　この内視鏡湾曲部は、筒状部（２８）を有し互いに共軸に並設されている複数の節輪（２６ａ，２６ｂ）を有し、隣り合う両節輪（２６ａ，２６ｂ）の内の一方の節輪（２６ａ）は、筒状部（２８）と一体的に設けられ筒状部（２８）の径方向に延びている突出部（３２）を有し、隣り合う両節輪（２６ａ，２６ｂ）の内の他方の節輪（２６ｂ）は、筒状部（２８）と一体的に設けられ突出部（３２）が突出部（３２）の長手軸を中心として回動可能に挿入されている受部（４２）を有し、各節輪（２６ａ，２６ｂ）は、筒状部（２８）において筒状部（２８）の周方向に対して交差して延びる非接合あるいは接合済の不連続部（３４）を有する。
