PROBLEM TO BE SOLVED: To provide an endoscope allowing a certain operation by preventing that the positional shift between a base plate and a casing occurs by pulling of the base plate by a holding case to prevent that the movement of an operation means fixed to the base plate becomes bad.SOLUTION: An operation part has: a body casing having an opening part for a base plate the plate-like base plate disposed inside the body casing, and having a projection part projecting outward from the opening part for the base plate a cylindrical member which is nearly parallel with a plate face of the base plate and is fixed to the projection part of the base plate a holding case having a hollow part through which the projection part of the base plate and the cylindrical member are inserted and a fixing ring fixed to the cylindrical member in a state that the holding case is pressed against an opening face formed with the opening part for the base plate of the body casing. The base plate has, in a side face on a side on which the projection part is formed, abutment parts abutting on the opening face from inside the body casing.COPYRIGHT: (C)2013,JPO&INPIT【課題】地板が把持ケースに引っ張られて、地板とケーシングとの位置ズレが生じることを防止して、地板に固定されている操作手段の動きが悪くなることを防止して、確実な操作ができる、内視鏡を提供する。【解決手段】操作部が、地板用開口部を有する本体ケーシングと、本体ケーシング内に配置され、地板用開口部から外側に突出する突出部を有する板状の地板と、軸を地板の板面と略平行にして、地板の突出部に固定される筒状部材と、地板の突出部および筒状部材が挿通される中空部を有する把持ケースと、把持ケースを本体ケーシングの地板用開口部が形成された開口面に押し当てた状態で、筒状部材に固定される固定リングとを有し、地板が、突出部が形成される側の側面に、本体ケーシングの内側から開口面に当接する当接部を有することにより、前記課題を解決する。【選択図】図2
