PROBLEM TO BE SOLVED: To provide an endoscope capable of rotating a captured image at any angle while maintaining the imaging direction with an insertion section being bent.SOLUTION: The endoscope comprises: an insertion section 5 configured to be bendable, extend from a base end 5a to a free end 5b, and be rotatable about the extension direction thereof a functional member (imaging unit 6a) disposed in the side of the idle end 5b a plurality of control wires 20, the trailing ends of which are fixed to the side of the idle end 5b and a traction member 8 disposed in the side of the base end 5a and configured to pull the starting ends of the plurality of control wires 20 so as to bend the insertion section 5. When the insertion section 5 is rotated, the functional member (imaging unit 6a), the plurality of control wires 20, and the traction member 8 are rotated along with the insertion section 5. The traction member 8 maintains the bending direction and the bending angle of the insertion section 5 by changing the traction quantity with respect to the plurality of control wires 20.COPYRIGHT: (C)2015,JPO&INPIT【課題】挿入部が湾曲した状態で、撮像方向を維持したままで撮像された画像を任意の角度に回転させることが可能な内視鏡を提供すること。【解決手段】湾曲可能で、基端5aから遊端5bにかけて延在するとともに、その延在する方向を軸として回動可能な挿入部5と、前記遊端5bの側に設けられた機能部材(撮像ユニット6a)と、前記遊端5bの側に終端が固定された複数の制御ワイヤ20と、前記基端5aの側に設けられ、前記挿入部5を湾曲させるべく前記複数の制御ワイヤ20の始端側を牽引する牽引部材8とを備え、前記挿入部5が回動するとき、前記機能部材(撮像ユニット6a)、前記複数の制御ワイヤ20および前記牽引部材8は前記挿入部5とともに回動し、前記牽引部材8は前記複数の制御ワイヤ20に対する牽引量を変化させて、前記挿入部5の湾曲方向および湾曲角度を維持する。【選択図】図9
