PROBLEM TO BE SOLVED: To provide an endoscope of which insertion part includes a bendable section and a soft section that are separably but firmly joined together.SOLUTION: A connection ring 30 of a bendable section 11 and a connection ring 29 of a soft section 12 are engaged with each other. The connection ring 29, disposed in an inner engaging side, has a plurality of circumferentially spaced engaging holes 234. The connection ring 30, disposed in an outer engaging side, has a plurality of engaging pieces which are cut out from the connection ring 30 and bent toward the inner diameter side for insertion into the engaging holes 234. The plurality of engaging pieces includes at least one first engaging piece 230 which extends in an axial direction of the connection ring 30 and at least one second engaging piece 231 which extends in a circumferential direction of the connection ring 30.SELECTED DRAWING: Figure 25COPYRIGHT: (C)2016,JPO&INPIT【課題】挿入部の湾曲部と軟性部とが分離可能に強固に接合された内視鏡を提供する。【解決手段】互いに嵌合される湾曲部11の接続環30及び軟性部12の接続環29のうち嵌合内側に配置される接続環29には、周方向に間隔をあけて複数の係合孔234が設けられており、嵌合外側に配置される接続環30には、接続環30から切り出され、内径側に折り曲げられて係合孔234に挿し込まれる複数の係合片が設けられており、複数の係合片は、接続環30の軸方向に延設される少なくとも一つの第1係合片230、及び接続環30の周方向に延設される少なくとも一つの第2係合片231を含む。【選択図】図25
