ABSTRACT:
A bending device for use in an endoscope, a catheter or the like is of a simple construction having a coil, an operating wire and a pair of limitation members for limiting an axial compression of the coil. The pair of limitation members are arranged along the length of the coil, and are mounted respectively on diametrically-opposite portions of the coil. The coil is bendable in a direction perpendicular to a plane in which the pair of limitation members are disposed. Instead of the coil, a bellows can be used.
