PROBLEM TO BE SOLVED: To provide an operation wire connection structure of an endoscope which is capable of surely preventing loosening of connection and easily releasing the connection.SOLUTION: A connection structure 40 includes: a cylinder member 41 disposed at one of a first operation wire 31 and a second operation wire 33 a core member 43 disposed to the other one of the first operation wire 31 and the second operation wire 33, and connected with the cylinder member 41 by being screwed to the cylinder member 41 and a heat-shrinkable tube 45 covering the connected cylinder member 41 and core member 43, closely attached to the cylinder member 41 and the core member 43 by being shrunk by heating, and preventing one of the connected cylinder member 41 and core member 43 from being rotated to the other when closely attached. The heat-shrinkable tube 45 includes a string-like member 45k disposed on the inner peripheral surface side of the heat-shrinkable tube 45, for incising the heat-shrinkable tube 45 closely attached to the cylinder member 41 and the core member 43, by being pulled.COPYRIGHT: (C)2014,JPO&INPIT【課題】 接続の緩みを確実に防止でき、且つ接続を簡単に分解できる内視鏡の操作ワイヤ接続構造を提供すること。【解決手段】 接続構造40は、第1の操作ワイヤ31と第2の操作ワイヤ33との一方に配設されている筒部材41と、第1の操作ワイヤ31と第2の操作ワイヤ33との他方に配設され、筒部材41に螺合することによって筒部材41と連結する芯部材43と、連結している筒部材41と芯部材43とを覆い、加熱によって収縮することで筒部材41と芯部材43とに密着し、密着した際に連結している筒部材41と芯部材43との一方が他方に対して回転することを防止する熱収縮チューブ45と、を有している。熱収縮チューブ45は、熱収縮チューブ45の内周面側に配設され、引っ張られることによって筒部材41と芯部材43とに密着している熱収縮チューブ45を切開するひも状部材45kを有している。【選択図】 図3D
