    • First stepped portions are provided on both sides of each of two front-side projection portions of a front end portion of a node ring. Second stepped portions are provided on both sides of each of two rear-side projection portions of a rear end portion of the node ring. At a time of bending of a bending section, when two front and rear node rings of a bending tube are rotated to a maximum rotational position, the pivotal angle α between the front and rear node rings is restricted to a predetermined restriction angle that prevents, when the bending section is bend-operated, an outer sheath tube from being bitten between the node rings, by the restriction due to contact between the second stepped portion of the front-side node ring and the first stepped portion of the rear-side node ring.
