摘要：
PROBLEM TO BE SOLVED: To provide an endoscope which prevents liquid leakage in the hydraulic system for driving the bending of a bend.SOLUTION: An endoscope 1 comprises: an actuator 21 which is disposed in a base end side of a bend 12 of an insertion section 2 and exerts the drive to bend the bend 12, the actuator 21 having a fixing member 32 secured with respect to the insertion section 2 and a movable member 31 movable relative to the fixing member 32 along the axial direction of the insertion section 2 a rod 22 for transferring the movement of the movable member 31 to a bend mechanism, the base end part thereof being secured to the tip end part of the movable member 31 and tip end part thereof being secured to a bend mechanism of the bend 12 a tube 23 connected to the fixing member 32 for allowing a liquid to be supplied to the fixing member 32 so that the movable member is moved by the pressure of the liquid and a seal member 34 for preventing the leakage of the liquid which moves the movable member 31.COPYRIGHT: (C)2015,JPO&INPIT【課題】湾曲部の湾曲駆動のための油圧システムにおける液漏れを防止する内視鏡を提供する。【解決手段】内視鏡1は、挿入部2の湾曲部12の基端側に設けられ、挿入部2に対して固定された固定部材32と、固定部材32に対して挿入部2の軸方向に沿って移動可能な可動部材31とを有し、湾曲部12を湾曲させるように駆動するためのアクチュエータ21と、基端部が可動部材31の先端部に固定され、先端部が湾曲部12の湾曲機構に固定されて、可動部材31の動きを湾曲機構に伝達するロッド22と、可動部材31を液体の圧力で動かすために、固定部材32に液体を供給するために固定部材32に接続されたチューブ23と、可動部材31を動かす液体が漏れ出さないように設けられたシール部材34とを有する。【選択図】図3
