PROBLEM TO BE SOLVED: To provide a fiber scope (long tool) in which the flexibility of an insertion portion (soft portion) can be prevented from being deteriorated, compared with conventional ones.SOLUTION: A fiber scope includes: an operation portion 2 to be operated by a user an insertion portion 3 having a movable portion 5 extending from the operation portion 2 and being operable so as to be bent to a front portion 3a side, and having a deformable soft portion 6 formed on the side from the movable portion 5 to the operation portion 2 and a drive mechanism portion 4 for operating the movable portion 5 so as to be bent. The drive mechanism portion 4 has: an operation wire 11 which operates the movable portion 5 so as to be bent an air cylinder 12 which is incorporated in the vicinity of the movable portion 5 and pulls the operation wire 11 and a tube 13 which supplies air to the air cylinder 12 and can be deformed by following the soft portion 6. The tube 13 is formed along the soft portion 6 from the air cylinder 12 to the operation portion 2 side.COPYRIGHT: (C)2014,JPO&INPIT【課題】ファイバスコープ(長尺ツール)において、従来に比べて、挿入部(軟性部)の可撓性が低下するのを抑える。【解決手段】ユーザが操作する操作部2と、この操作部2から延び先部3a側に湾曲動作可能な可動部5を有しかつ変形自在な軟性部6を可動部5から操作部2側に有している挿入部3と、可動部5を湾曲動作させる駆動機構部4とを備えている。駆動機構部4は、可動部5を湾曲動作させる操作ワイヤ11と、可動部5の近傍に組み込まれ操作ワイヤ11を引っ張るエアシリンダ12と、エアシリンダ12にエアを供給すると共に軟性部6に追従して変形可能なチューブ13とを有している。チューブ13は、エアシリンダ12から操作部2側まで軟性部6に沿って設けられている。【選択図】 図2
