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 jointed together with at least one screw 260. In the connection ring 29, disposed in an inner engaging side, an engaging portion 29a overlapping with the connection ring 30 disposed in an outer engaging side has through-holes 263 into which the screw shaft portion 262 of the screw 260 is inserted and which engages the screw head portion 261. In the connection ring 30, an engaging portion 30a overlapping with the connection ring 29 is formed thicker than at least a portion of the part excluding the engaging portion 30a of the connection ring 30, and has screw holes 264 which overlap with each of the through-holes 263 when overlapping with the engaging portion 29a of the connection ring 29, and which engage the screw shaft part 262.SELECTED DRAWING: Figure 26COPYRIGHT: (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】湾曲部11の接続環30と軟性部12の接続環29とは、少なくとも一つのネジ260によって互いに連結されており、嵌合外側に配置される接続環29において、嵌合内側に配置される接続環30と重なる嵌合部29aには、ネジ260のネジ軸部262が挿通され且つネジ頭部261と係合する貫通孔263が設けられており、接続環30において接続環29と重なる嵌合部30aは、接続環30の嵌合部30aを除く部分の少なくとも一部より肉厚に形成され、この嵌合部30aには、接続環29の嵌合部29aと重なった状態で貫通孔263の各々に重なり、ネジ軸部262と螺合するネジ孔264が設けられている。【選択図】図26
