- 摘要：
PROBLEM TO BE SOLVED: To provide an endoscope guide tube that has a simple structure and is highly operable even with considerable narrower diameter, and an endoscope device having the endoscope guide tube, and to provide a tube-bending machine.
SOLUTION: The endoscope guide tube 7 includes a tube member 10, in which the insertion part 2 of the endoscope is inserted and which has a curved part 9 formed at least at its leading end. The tube member 10 has: a thin heat contraction tube (bend-retaining layer) 11 for retaining the curved state of the curved part 9 and a net pipe (stress relaxing layer) 12 elastically deformed to disperse the bending stress applied, when the curved part 9 is bent in a direction where the curve of the curved part 9 is relaxed.
