PROBLEM TO BE SOLVED: To provide a flexible tube bending device excellent in the operability, preventing curving and bending of other portions other than a bending part at the distal end by a simple structure.
SOLUTION: A first operation wire hole 5 penetrating in the axial direction is bored in a flexible tube 2 composed of the bending part 8 on the distal end side, a connection part 9 on the proximal end side and a bending transition part 10 in-between. The first operation wire hole 5 is formed of a first operation wire hole distal end part 5a bored parallel to a center axis C at a position eccentric to the outer side from the center axis C of the flexible tube 2 in the bending part 8, a first operation wire hole base part 5b bored on the center axis C of the flexible tube 2 in the connection part 9, and a first operation wire hole inclined part 5c bored to be inclined in such a way that the first operation wire hole distal end part 5a communicates with the first operation wire hole base part 5b in the bending transition part 10. A first operation wire 4 whose distal end is attached to the distal end of the flexible tube 2 and whose proximal end is attached to an operation part 3 within the first operation wire hole 5 is pulled by the operation part 3, so that the bending part 8 is bent.
