１記載の内視鏡の湾曲装置。[Claims for Utility Model Registration] (1) A plurality of joint rings are rotatably connected to form a curved portion, an operating wire is inserted through a wire guide provided in the joint rings, and the operating wire is A bending device for an endoscope, which bends the bending portion by pulling the bending portion, and limits the maximum bending angle in at least one direction to be smaller than the sum of bendable angles of the nodal rings in that direction. In this method, a coil spring having a free length approximately equal to the distance between adjacent wire guides is interposed between adjacent wire guides in a portion that is most easily bent when the curved portion is bent. Endoscope bending device. (2) The curved portion is configured to curve at least in the vertical direction, each of the node rings is vertically symmetrical, and the maximum curving angle in one of the vertical directions is set smaller than the maximum curving angle in the other. The endoscope bending device according to claim 1.
