PROBLEM TO BE SOLVED: To provide an endoscope which enables the operator to intuitively ensure that an insertion portion is rotated to a desired angle relative to the operation portion before using the endoscope.SOLUTION: The endoscope comprises: an operation-portion-side ferrule pipe 3P fixed to an operation portion body 3M an insertion-portion-side ferrule pipe to which a flexible tube portion 7 of an insertion portion is integrally fixed an index ring fixing member 22 which is rotatably arranged relative to the first pipe 3P and to which an index ring 20 is integrally fixed a rotation knob fixing member 32 to which an insertion portion rotation knob 30 is integrally fixed and which is integrally fixed to the first pipe 3P a sliding protrusion which comes into contact with any one of the index ring fixing member 22 and the rotation knob fixing member 32 a leaf spring provided with a fitting portion which is fixed to a member different from the member with which the protrusion comes into contact and a through hole that is disposed at a predetermined position of the index ring fixing member 22 or the rotation knob fixing member 32 with which the protrusion comes into contact, and that changes the contact state of the protrusion according to the rotation of the insertion-portion-side ferrule pipe.COPYRIGHT: (C)2015,JPO&INPIT【課題】挿入部が操作部に対して術者の所望する角度まで回転したことを感覚的に把握して操作することが可能な内視鏡を提供する。【解決手段】内視鏡は、操作部本体3Mに固設された操作部口金パイプ3Pと、挿入部2の可撓管部7が一体に固設される挿入部口金パイプと、第1パイプ3Pに対して回動可能に設けられ、指標環20が一体に固設される指標環固定部材22と、挿入部回動つまみ30が一体に固設され、第1パイプ3Pに対して一体に固設される回動つまみ固定部材32と、指標環固定部材22又は回動つまみ固定部材32の何れか一方に当接する摺動突起、及び、突起が当接した部材とは異なる部材に固定される取付部を具備する板バネと、突起が当接する指標環固定部材22又は回動つまみ固定部材32の予め定めた位置に設けられ、挿入部口金パイプの回動に応じて突起の当接状態を変化させる貫通孔と、を具備する。【選択図】図2
