Summary:Provided is an endoscope bending operation mechanism provided with: a first pulley (15) that tows a first wire (10a) by rotating in a first rotation direction; a second pulley (16) that tows a secondwire (10b) by rotating in a second rotation direction opposite to the first rotation direction and in which the rotation center is coaxial with the first pulley (15); and a rotation shaft member (13)that engages with only the first pulley (15) during rotation in the first rotation direction and engages with only the second pulley (16) during rotation in the second rotation direction from a neutral position at which a bending part is not bent. 本发明提供一种内窥镜的弯曲操作机构，其具有：通过向第一旋转方向旋转而牵拉第一操作线(10a)的第一滑轮(15)；通过向与第一旋转方向相反的第二旋转方向旋转而牵拉第二操作线(10b)的、旋转中心与第一滑轮(15)同轴的第二滑轮(16)；和从弯曲部不弯曲时的中立位置向第一旋转方向旋转时仅与第一滑轮(15)卡合、向第二旋转方向旋转时仅与第二滑轮(16)卡合的旋转轴部件(13)。
