PROBLEM TO BE SOLVED: To provide a component fixing structure of an endoscope capable of restraining wasteful replacement of a member to be fixed by preventing the member to be fixed from being damaged by attaching and detaching a fixing member.SOLUTION: A component fixing structure of an endoscope includes: a first member 21 to be fixed provided with a hole 23 a second member 31 to be fixed fitted in the first member 21 to be fixed and provided with a recessed part 33b formed at a position opposite and superposed on the hole 23 and a fixing member 50 inserted in the hole 23 and provided with a projecting part engaged with the recessed part 33b. The fixing member 50 is turned at a predetermined angle and the projecting part is shaved or deformed by an opening corner part in the inside diameter part in the hole 23 of the first member 21 to be fixed superposed on the recessed part 33b to come into contact therewith, thereby preventing the fixing member 50 from slipping off. The second member 31 to be fixed is pressed in the radial direction to fix the first member 21 to be fixed and the second member 31 to be fixed, thereby preventing the second member 31 to be fixed from slipping off from the first member 21 to be fixed.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し、被固定部材の無駄な交換が抑えられる内視鏡の部品固定構造の提供。【解決手段】内視鏡の部品固定構造は、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31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に重畳する第1の被固定部材21の孔部23における内径方向の開口角部に削られるまたは変形して接触することで、固定部材50の抜けが防止され、第2の被固定部材31を径方向に押圧して第1の被固定部材21と第2の被固定部材31とを固定して、第2の被固定部材31が第1の被固定部材21からの抜けを防止する。【選択図】図6
