PROBLEM TO BE SOLVED: To provide a component fixing structure of an endoscope, capable of suppressing useless replacement of a member to be fixed and reducing costs of repair and maintenance or the like by the configuration of preventing the member to be fixed from being damaged by attachment and detachment of a fixing member.SOLUTION: The fixing structure of an endoscope includes: a first member 21 to be fixed, where a hole part 23 is formed a second member to be fixed, which is inserted and fitted to the first member 21 to be fixed and has a recessed part 33b formed at a position to be superimposed facing the hole part 23 and a fixing member 50 which has a projection part to be inserted to the hole part 23 and engaged with the recessed part 33b. The fixing member 50 is rotated at a prescribed angle and the projection part is scraped or deformed by a wall surface forming the recessed part 33b, made into a plane and brought into surface contact, and thus the first member 21 to be fixed and the second member to be fixed are fixed.COPYRIGHT: (C)2013,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、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を提供する。【解決手段】内視鏡の固定構造は、孔部23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に挿嵌されて、孔部23と対向して重畳する位置に凹部33bが形成された第2の被固定部材と、孔部23に挿入されて、凹部33bに係入される凸部を有する固定部材50と、を具備し、固定部材50が所定の角度で回転され、凸部が凹部33bを形成する壁面に削られるまたは変形して平面化して面接触することで第1の被固定部材21と第2の被固定部材とを固定する。【選択図】図6
