PROBLEM TO BE SOLVED: To provide an endoscope, a part fixing structure for an endoscope, and a part fixing method for an endoscope capable of reliably fixing the insertion member, such as an operation wire or a wire guide tube, which is inserted into the insertion part of an endoscope, and also capable of widening the internal space of the insertion part.SOLUTION: The distal end part of an operation wire 40 which bends the bending part and the distal end part of a wire guide tube 42 through which the operation wire is inserted are fixed respectively to the distal end ring 32 and the proximal end ring 34 of the bending part by way of sleeves 84, 60. The sleeves 84, 60 are formed in a cylindrical shape and hold the operation wire 40 or the wire guide tube 42 by externally fitting to the distal end part of the operation wire 40 or wire guide tube 42. The center side partition wall of the insertion part in an axially vertical cross section is notched axially to form a slit 86 for communication between the interior and the exterior. The circumferential width of the axially vertically formed opening of the slit 86 is configured smaller than the outer diameter of the distal end part of the operation wire 40 or wire guide tube 42 which is inserted through the sleeve.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2016,JPO&INPIT【課題】内視鏡の挿入部の内部に挿通される操作ワイヤ又はワイヤガイド管等の挿通部材を確実に固定することができ、かつ、挿入部の内部スペースを広くすることができる内視鏡、内視鏡の部品固定構造、及び内視鏡の部品固定方法を提供する。【解決手段】湾曲部を湾曲させる操作ワイヤ40の先端部と、操作ワイヤが挿通されるワイヤガイド管42の先端部は、湾曲部の先端リング32と基端リング34にスリーブ84、60を介して固定される。スリーブ84、60は、筒状に形成され、操作ワイヤ40又はワイヤガイド管42の先端部を外嵌して保持する。また、軸方向に垂直な断面において挿入部の中心側の隔壁が軸方向に沿って切り欠かれ内部と外部を連通するスリット86を有し、スリット86の軸方向に垂直な周方向の開口幅はスリーブに挿通される操作ワイヤ40又はワイヤガイド管42の先端部の外径よりも小さく構成される。【選択図】図5
