PROBLEM TO BE SOLVED: To provide an endoscope capable of two operation methods, that is, a manual operation method by an operator himself and an operation method with the help of a person other than the operator. SOLUTION: An endoscope 10 is provided from an insertion portion having a soft portion, an operation portion 14 connected to the base end side of the insertion portion, and the operation portion 14 to the soft portion, and adjusts the hardness of the soft portion. The hardness adjusting mechanism 50, the operation ring 30 as the first driving force input member provided in the operation unit 14 and manually operating the hardness adjusting mechanism 50 to input the driving force, and the operation ring 30 are Separately provided, it has a shaft 36 as a second driving force input member for inputting a driving force to the hardness adjusting mechanism 50. [Selection diagram] Fig. 3【課題】硬度調整操作に関して、術者自身の手動による操作方法と、術者以外の手を借りる操作方法の２つの操作方法が可能な内視鏡を提供する。【解決手段】内視鏡１０は、軟性部を有する挿入部と、挿入部の基端側に連設された操作部１４と、操作部１４から軟性部にかけて設けられ、軟性部の硬度を調整する硬度調整機構５０と、操作部１４に設けられ、手動操作されることによって硬度調整機構５０に対して駆動力を入力する第１駆動力入力部材としての操作リング３０と、操作リング３０とは別に設けられ、硬度調整機構５０に対して駆動力を入力する第２駆動力入力部材としてのシャフト３６とを、を有する。【選択図】図３
