Abstract
An endoscope includes a manipulation unit, and an insertion unit which is disposed in continuation to the manipulation unit. The insertion unit contains a bending portion which has a plurality of articulation wheels coupled in succession, two adjacent ones of the articulation wheels being coupled by a shaft member so as to be relatively turnable around the shaft member which crosses the center axis of the bending portion, the bending portion being bent in such a way that a wire which leads to the manipulation unit via the plurality of articulation wheels is tractively manipulated. The shaft member has a guide part formed with an insertional hole through which the wire is inserted, and at least the guide part of the shaft member is turnable around the center axis of the shaft member, to both the two articulation wheels coupled by the shaft member.
