Abstract
A bending device for use in an endoscope, a catheter or the like includes a frame of a generally cylindrical shape, a limitation member and an operating wire. The frame has annular portions disposed respectively in planes substantially perpendicular to an axis of the frame, and the annular portions are juxtaposed in an axial direction of the frame. The limitation member is received in an internal space of the frame, and engaging recesses are formed in each of opposite lateral edges of the limitation member and juxtaposed in a longitudinal direction of the limitation member. The annular portions of the frame are engaged in the engaging recesses, so that any adjacent ones of the annular portions are spaced a predetermined distance from each other. The limitation member has a number of arcuate portions bulged generally perpendicularly to the direction of the length of the limitation member, and the arcuate portions are juxtaposed in the longitudinal direction of the limitation member. The limitation member is mounted on the frame in such a manner that the arcuate portions are resiliently deformed, so that the opposite lateral edges of the limitation member are urged away from each other and resiliently held against an inner periphery of each of the annular portions.
