An endoscope includes a first pulling section, an first elongated member, a restricting portion, a sliding surface, and a partition. The restricting portion is provided inside the operation section, and is configured to restrict a position of the first pulling section. The sliding surface is provided in the restricting portion, and allows the first pulling section to move along the axial direction. The partition covers at least a part of the sliding surface and the first pulling section, and is configured to partition the first elongated member and the first pulling section. The partition and the restricting portion are configured to restrict a moving range of the connection portion within a range of the sliding surface.

Endoscope

An endoscope including a bending portion in an insertion portion comprises multiple pulling members, an operation device, a driving force transfer mechanism and a biasing mechanism. The multiple pulling members are mounted on the bending portion. The operation device generates a driving force for pulling the pulling members in conjunction with a turning operation. The bending portion is bent by the operation device between an approximately straight state and a bending state. The driving force transfer mechanism transfers the driving force generated in conjunction with the turning operation of the operation device to the pulling members. The biasing mechanism provides the driving force transfer mechanism with a biasing force for turning the operation device in a reverse direction to the turning operation direction in a state where the bending portion is bent by turning the operation device.

An adapter for an endoscope of the present invention includes: a locking device for attaching and detaching that attaches and locks this adapter for an endoscope onto a predefined position on an endoscope control part; and a first treatment tool locking device that keeps a treatment tool at a first predefined position. Furthermore, at the first predefined position, a guidewire entry aperture of the treatment tool and an entry aperture of a forceps plug are separated in such a way as to face each other along substantially the same line.
