A bending device includes a bellows with an internal space, an operating wire for bending the bellows, and multiple pairs of independent limitation structures for limiting an axial compression of the bellows. The bellows includes a corrugated peripheral wall defined by first portions that bulge radially outward and are arranged alternately with second portions that bulge radially inward. The peripheral wall has first and second regions, each of which includes a predetermined number of alternating first and second portions. A pair of limitation structures are mounted on diametrically-opposite sections of each of the first regions and on diametrically-opposite sections of each of the second regions. The sections of each first region are spaced from each other in a first direction while the sections of each second region are spaced from each other in a second direction.
