An endoscope comprising:
- an inserted portion that has, sequentially from a distal-end side, a distal-end portion, a bending portion that changes an orientation of the distal-end portion, and an elongated flexible portion having flexibility;
- a wire that has an exposed portion that is disposed outside the distal-end portion of the flexible portion along a longitudinal direction of the flexible portion, and in which positions of the exposed portion, at a predetermined first position and a predetermined second position that is separated from the first position on a base-end side, are restrained with respect to the distal-end portion of the flexible portion in a radial direction;
- and
- a wire adjusting portion that changes a length between the first position and the second position of the wire.
An overtube comprising:
- a cylindrical main unit that has a pathway that is formed so as to pass therethrough in a longitudinal direction and into which a wire and an elongated flexible portion provided in an endoscope are inserted;
- and
- a securing portion that is provided at a base-end portion of the main unit and that secures an intermediate position of the wire to the main unit.
