PROBLEM TO BE SOLVED: To maintain flexible bendabilities without deforming a connecting shaft if force to compress a flexible tube in the axial direction is applied by an autoclave or the like in the flexible endoscope tube using a flexible tube frame body in which a plurality of joint pieces are rotatably connected by the connecting shaft. SOLUTION: In the flexible endoscope tube in which the adjacent joint pieces 7 are mutually connected to rotate by the connecting shaft 75 fit in a connecting hole 74 formed at least on one tongue piece 72 of superposed tongue pieces 72, 73 from the side of the other tongue piece 73, when the force to compress the flexible endoscope tube in the axial direction acts, a protruding end edge of the outer tongue piece 73 abuts on a recessed step part 71 of the inner tongue piece 72 at the part where the tongue pieces 72, 73 are mutually superposed before the outer peripheral surface of the connecting shaft 75 is pressed against the inner peripheral surface of the connecting hole 74 so that a state in which the outer peripheral surface of the connecting shaft 75 is pressed against the inner peripheral surface of the connecting hole 74 is prevented.
