Claims

[Scope of utility model registration request]

A flexible tube section 2 that is connected to the operation section main body 1 has a curved section 3 at the tip, and by rotating a knob 5 provided on the operation section main body 1, the E is emitted from the operation section main body 1 through the flexible tube section 2. In an endoscope equipped with a cable 13.23 that gives a bending motion to the bending section 3, a rotating shaft 6 that is rotated by rotation of the knob 5 is provided in the operating section main body 1. A double drum consisting of a grooved drum 11.21 is fixed to the drum 11.21, and elastic wires 12.22 wound in opposite directions are connected to the cables 13 and 23, respectively, on each drum 11.21. The winding action of one elastic filament gives relaxation to the other leaf spring, and this slack is formed as an expansion of the winding diameter of the four elastic filaments around the drum, and the rope to be relaxed is The bending operation device is configured to absorb and remove the remaining slack after the necessary feed amount by expanding the diameter of the winding while applying a required tension to the cable.
