Abstract: In a bending tube for endoscope on which torsion preventing tab mechanisms are provided on the respective middle parts of first and second slots for bending located in an area from the proximal end of a bending tube body to a predetermined position on the distal end side (the torsion suppressing area), and the bending tube body being permitted to bend by the first and second slots for bending, the torsion preventing tab mechanism of at least any one of the first and second slots for bending arranged on the proximal end side of each of arrays (first and second arrays), other than the first and second slots for bending located at the most proximal end, among the first and second slots for bending arrayed in a same line, respectively, along a longitudinal direction of the bending tube body, is removed.
