There is provided a bending tube for endoscope the durability of which can be enhanced without decreasing the torsional rigidity around an axis more than necessary. For this purpose, in the bending tube for endoscope 30 on which torsion preventing tab mechanisms 35 are provided on the respective middle parts of first and second slots for bending 33 and 34 located in an area from the proximal end of the bending tube body 31 to a predetermined position on the distal end side (the torsion suppressing area A3), and the bending tube body 31 being permitted to bend by the first and second slots for bending 33 and 34, the torsion preventing tab mechanism of at least any one of the first and second slots for bending 33 and 34 arranged on the proximal end side of each of arrays (first and second arrays), other than the first and second slots for bending 33 and 34 located at the most proximal end, among the first and second slots for bending 33 and 34 arrayed in a same line, respectively, along a longitudinal direction of the bending tube body 31, is removed. |
