PROBLEM TO BE SOLVED: To provide an endoscope capable of adjusting the tension of a tugging member and capable of making it hard to apply loads to the tugging member when a tugging mechanism is activated.SOLUTION: An endoscope includes an insertion section, an operation input section, a tugging member, a tugging mechanism and a coupling mechanism. The insertion section includes a distal end hard part, and a bending section which can be bent in a plurality of directions. One end of the tugging member is coupled to the distal end hard part or bending section, and the other end is extended toward the operation input section. The tugging mechanism can tug one end of the tugging member according to the input of operation of the operation input section. The coupling mechanism is disposed between the other end of the tugging member and the tugging mechanism. The coupling mechanism has a slider mechanism to relatively move the other end of the tugging member and the tugging mechanism in the axial direction of the tugging member. The coupling mechanism has an adjusting mechanism provided in the slider mechanism for adjusting the tension of the tugging member between the slider mechanism and one end of the tugging member while the tugging member is tugged.COPYRIGHT: (C)2013,JPO&INPIT【課題】牽引部材の張り具合を調整可能で、かつ、牽引機構を動作させたときに牽引部材に負荷をかけ難くすることが可能な内視鏡を提供する。【解決手段】内視鏡は、挿入部と操作入力部と牽引部材と牽引機構と連結機構とを有する。挿入部は、先端硬質部と、複数の方向に湾曲可能な湾曲部とを有する。牽引部材は先端硬質部又は湾曲部に一端が連結され、他端が操作入力部に向かって延出されている。牽引機構は操作入力部の操作の入力に応じて牽引部材の一端を牽引することが可能である。連結機構は、牽引部材の他端と牽引機構との間に配設されている。連結機構は牽引部材の他端と牽引機構とを牽引部材の軸方向に相対的に移動させるスライダ機構を有する。連結機構は、スライダ機構に設けられ牽引部材を牽引した状態でのスライダ機構と牽引部材の一端との間の牽引部材の張り具合を調整する調整機構を有する。【選択図】図3A
