摘要：PROBLEM TO BE SOLVED: To provide an endoscope bending tube beingbendable by providing a plurality of slots, and having excellent bending properties, whileimproving torsional resistance of a pipe.SOLUTION: An endoscope bending tube 9includes: a hard pipe 10 that is bendable by forming slots 11 and 12 for communicating anouter peripheral surface and an inner peripheral surface, along the circumference of thepipe; distal-side ridge portions 11f and 12f constituting a distal-side ridge; proximal-sideridge portions 11e and 12e constituting a proximal-side ridge and coming into contactwith the distal-side ridge portions 11f and 12f; a bending wire 8 disposed in the hard pipealong a pipe longitudinal axis for bending the hard pipe 10; a locking recess 14 formedinto a recessed shape in a direction of a longitudinal axis; a locking projection 13

configured to be disposed in the locking recess 14; and a torsion regulation projection 32projecting in the direction of a central axis O1, further than the inner peripheral surface10f of the hard pipe 10, in the locking recess 14.SELECTED DRAWING: Figure 2
