Claims

[Claims for Utility Model Registration] An endoscope having an elongated insertion section, in which an operating mechanism provided at the distal end of the insertion section can be operated by operating a cable extending inside the insertion section, A clamping part that guides and clamps a guide tube that guides the cable in the longitudinal direction of the insertion part is provided on the inner circumferential wall of the cylindrical body that connects the distal end part and a flexible part connected to the rear of the distal end part. The endoscope is characterized in that the clamping part and the front end of the guide tube are fixed together.
