Abstract: A bending operation device includes a bending operation member, a bendable part, an operation wire, a pulling wire, and a connection member. The bending operation member is disposed in an operation unit and is supported tiltably in a preset direction. The bendable part is disposed on a side of a distal end of the operation unit. The operation wire is connected at an end thereof to the bending operation member and is pulled or relaxed according to displacement of the bending operation member. The pulling wire is connected to the bendable part and bends the bendable part. The connection member is connected to the operation wire at a first position and is connected to the pulling wire at a second position. The second position is shifted from the first position by a preset angle in a turning direction about a longitudinal axis of the operation unit.

Abstract: A bending operation device includes a bending operation lever, a wire pulling member, bending operation wires, and tubular members. The bending operation lever is tiltably supported to have an angle with respect to a longitudinal direction of an operation unit of an endoscope. The wire pulling member includes arm portions displaced in conjunction with tilt motion of the bending operation lever. The bending operation wires are connected to the arm portions. The bending operation wires cause bending motion of a bendable part disposed in an insertion section of the endoscope. A respective one of bending operation wires is inserted in each of the tubular members. The tubular members (i) change extension directions of the plurality of bending operation wires and (ii) guide the plurality of bending operation wires to the plurality of arm portions.

Abstract: An endoscope includes an insertion unit, an operation unit, an operation-unit engagement part, an insertion-unit engagement part, a water-tight sealing member, and a torque control member. The torque control member is provided between the operation-unit engagement part and the insertion-unit engagement part in radial directions of the insertion unit, so as to make tight contact with the operation-unit engagement part and the insertion-unit engagement part, and controls resistive torque of the insertion unit during rotation of the insertion unit by applying frictional resistance of a direction about the axis to the insertion unit when the insertion unit rotates in relation to the operation unit.
Abstract translation: 内窥镜包括插入单元，操作单元，操作单元接合部，插入单元接合部，防水密封构件和扭矩控制构件。 转矩控制部件在插入部的径向方向上设置在操作部卡合部和插入部卡合部之间，与操作部卡合部和插入部卡合部紧密接触， 当所述插入单元相对于所述操作单元旋转时，通过在所述插入单元的旋转期间施加围绕所述轴线的方向的摩擦阻力来控制所述插入单元在所述插入单元旋转期间的阻力矩。
