Abstract
An endoscopic bendable tube includes: an integrally formed resin tube; at least two wires embedded in a tube wall of the resin tube from a proximal end side to a distal end side of the resin tube, the at least two wires being parallel to a tube axis direction of the resin tube and being at positions facing each other; and a plurality of pairs of through slits formed in the tube wall of the resin tube in the tube axis direction, each pair of through slits being formed facing each other in the tube wall of the resin tube.

An endoscopic bendable tube comprising:
- a resin tube extending in a longitudinal direction;
- at least two wires disposed in the resin tube to extend in the longitudinal direction from a proximal end side to a distal end side of the resin tube;
- and
- a plurality of slit pairs formed in a first area of a wall of the resin tube, the plurality of slit pairs arranged at intervals in the longitudinal direction of the resin tube, a first pair of slit ends oppose each other across a second area of the wall of the resin tube;
- wherein a second radial thickness of the wall of the resin tube in the second area is greater than a first radial thickness of the wall of the resin tube in the first area.
