PROBLEM TO BE SOLVED: To provide an endoscope, a part fixing structure for an endoscope, and a part fixing method for an endoscope capable of reliably fixing the insertion member, such as an operation wire or a wire guide tube, which is inserted into the insertion part of an endoscope, and also capable of widening the internal space of the insertion part.SOLUTION: The distal end part of an operation wire 40 which bends the bending part and the distal end part of a wire guide tube 42 through which the operation wire is inserted are fixed respectively to the distal end ring 32 and the proximal end ring 34 of the bending part by way of sleeves 84, 60. The sleeves 84, 60 are formed in a cylindrical shape and hold the operation wire 40 or the wire guide tube 42 by externally fitting to the distal end part of the operation wire 40 or wire guide tube 42. The center side partition wall of the insertion part in an axially vertical cross section is notched axially to form a slit 86 for communication between the interior and the exterior. The circumferential width of the axially vertically formed opening of the slit 86 is configured smaller than the outer diameter of the distal end part of the operation wire 40 or wire guide tube 42 which is inserted through the sleeve.SELECTED DRAWING: Figure 5 |
