PURPOSE:To constitute the endoscope so that a treating implement is protruded easily from an opening part, and excessive bending is not generated in the treating implement even if a raising stand is raised by dividing a treating implement-raising stand is divided into at least two and engaging them so as to be freely turnable. CONSTITUTION:In the tip of a tip fixing part 19 of a tip constituting part 6, a tip cover 20 is stuck and fixed, and also, a treating implement-raising stand 22 for raising a treating implement 21 is fixed so as to be freely turnable by a treating implement raising stand-fixing pin 23. The treating implement-raising stand 22 is divided into two of a tip member 22a and a base end member 22b and connected so as to be come freely turnable by a bending fixing pin 25. When the treating implement-raising stand 22 is raised by operating a raising knob connected to the tip member 22a through a wire 26, the base end member 22b turns centering around the treating implement raising stand-fixing pin 23, and also, the tip member 22a turns centering around the bending fixing pin 25, by which the treating implement 21 is bent. In this case, an angle for raising the base end member 22b becomes small, and an angle for raising the tip member 22a becomes large. |
