This invention as the bend is buckled is operated by manipulating the buckling function part, regards the endoscope device which possesses the operation section. Purpose of this invention is to offer the endoscope device where operativity has improved. In the additional direction where the portable possible buckling function part (28) being in specified basic direction the endoscope device is concatenated and possesses, is provided and is provided and differs, the interposition section which is interposed in tube intracavity (17) with, the interposition section (17) the function part where is gripped is manipulated in the operator (24) with, the endoscope which it possesses (16) the interposition section (17) the bend which it is buckled is operated (19) with, the operation section which is operated (32) with, the function part (24) the function part (24) vis-a-vis, basic direction the portable possible buckling function part (28)The bend (19) the buckling Drive feature which it buckles operates (50) with, the function part (24) the buckling function part for (28) according to the movement to additional direction with, the function part (24) the buckling function part for (28) according to the movement to basic direction the operation section (32) the Drive unit which is operated (60 70) With, it possesses.本発明は、湾曲操作部を操作することにより湾曲部が湾曲作動されると共に、作動部を有する内視鏡装置に関する。本発明の目的は、操作性の向上されている内視鏡装置を提供することである。内視鏡装置は、管腔内に挿入される挿入部(17)と、挿入部(17)に連結され操作者に把持操作される操作部(24)と、を有する内視鏡(16)を具備し、挿入部(17)に設けられ湾曲作動される湾曲部(19)と、作動される作動部(32)と、操作部(24)に設けられ操作部(24)に対して所定の基本方向に移動可能な湾曲操作部(28)であって、基本方向とは異なる追加方向に移動可能な湾曲操作部(28)と、操作部(24)に対する湾曲操作部(28)の基本方向への移動に応じて湾曲部(19)を湾曲作動させる湾曲駆動機構(50)と、操作部(24)に対する湾曲操作部(28)の追加方向への移動に応じて作動部(32)を作動させる駆動ユニット(60;70)と、を有する。
