- 摘要：
PROBLEM TO BE SOLVED: To reduce the number of components, and to facilitate the assembly in nodal rings used for a bending tube for an endoscope, the bending tube for the endoscope, and an endoscope apparatus.
SOLUTION: The bending tube for the endoscope is formed by using the nodal rings 12 including an annular nodal ring body part 13 made of a metal, an arm part 15 protruded in a direction nearly along a central axis O from an end surface 13b of the joint ring body part 13, a female type fitting part 16 having an opening 16a with a diameter expandable by the elastic deformation at a distal end of the arm part 15, and a male type fitting part 14 having a protruding distal end 14a which is protruded in a direction nearly along the central axis O from an end surface 13a of the nodal ring body part 13 and has a diameter contractible by the elastic deformation when being inserted into the opening 16a of the female type fitting part 16 of the nodal ring 12 of the connecting counterpart and a protruding constriction part 14b fit in the opening 16a of the connecting counterpart in the connecting direction and is used for a bending portion of the endoscope apparatus.
