PROBLEM TO BE SOLVED: To provide a fixing structure of endoscope components, having a configuration to prevent damage of fixing object members by attachment/detachment of a fixing member, suppressing a useless replacement of the fixing object members fixed to each other by the fixing member, and reducing costs for repair and maintenance.SOLUTION: A fixing structure of an endoscope 2 includes: a first fixing object member 21 formed with a recess 22 a second fixing object member 30 that covers the first fixing object member 21 and is formed with a hole part 31b facingly superposed on an outward side of the recess 22 and a fixing member 50 having a projection 53 to be inserted into the recess 22 and a pressing part 51 to be engaged with the hole part 51b. When the fixing member 50 is rotated by a prescribed angle θ, the pressing part 51 presses, by its contact with an edge part 31c forming the hole part 31b, the edge part 31c and the recess 22 to fix the first fixing object member 21 to the second fixing object member 30.COPYRIGHT: (C)2014,JPO&INPIT【課題】 固定部材の着脱により被固定部材が損傷することを防止する構成として、固定部材により互いが固定される被固定部材の無駄な交換が抑えられ、修理、メンテナンスなどの費用を低減する内視鏡の部品固定構造の提供。【解決手段】 内視鏡2の固定構造は、凹部22が形成された第1の被固定部材21と、第1の被固定部材21を覆い、凹部22の外方側に対向して重畳する孔部31bが形成された第2の被固定部材30と、凹部22に挿入される凸部53および孔部51bと係合する押圧部51を有する固定部材50と、を具備し、固定部材50が所定の角度θで回転されると、押圧部51が孔部31bを形成する縁辺部31cとの接触により、縁辺部31cおよび凹部22を押圧することで、第1の被固定部材21と第2の被固定部材30とを固定する。【選択図】図8
