Abstract
An endoscope includes an insertion section, a bending section, a bending operation section and a shift mechanism. The bending section includes a first bending section and a second bending section provided at a proximal end of the first bending section. The second bending section includes an actuation pipe interposed between an angle wire extending in the second bending section and a wire guide through the angle wire and guiding the angle wire, and supported to be moved in the extending direction of the wire guide with respect to the wire guide. A rigidity of the second bending section is shifted while the actuation pipe is moved in the extending direction of the wire guide.
