PROBLEM TO BE SOLVED: To clean a wide range by one operation while composing a narrow distal end section.SOLUTION: An endoscope apparatus includes: a channel 7 formed to penetrate an elongated insertion section in the longitudinal direction a nozzle 5 provided at the distal end of the insertion section in such a way as rotatable around an axis along the longitudinal direction of the insertion section and having a spout 5a communicating with the channel 7 and opened sideways relative to the axis and a rotational force generating means 10 provided integrally with the nozzle 5 for generating the rotational force around the axis by receiving the fluid pressure of a fluid flowing from the channel 7 toward the spout 5a.COPYRIGHT: (C)2014,JPO&INPIT【課題】先端部を細径の構成としつつ広範囲を一度の操作できれいにする。【解決手段】細長い挿入部に長手方向に貫通形成された流路7と、挿入部の先端に該挿入部の長手方向に沿う方向の軸を中心に回転可能に設けられ、流路7に連通するとともに軸に対して側方に開口する吐出孔5aを有するノズル5と、該ノズル5と一体に設けられ、流路7から吐出孔5aへ向かって流動する流体の流体圧力を受けて軸を中心とする回転力を発生する回転力発生手段10とを備える内視鏡装置を提供する。【選択図】図2
