Abstract
In an endoscope, an elastic member made of a super elastic alloy, for instance, bridges the distal end portion of an insertion portion and the proximal end portion of a tip portion so that a space portion having a given interval is formed in between. A curving mechanism advances or retreats a manipulation wire that extends from the tip portion to the proximal side of the insertion portion, whereby curving or bending occurs at the space portion between the tip portion and the insertion portion.
