Claims

[Claims for Utility Model Registration] (1) A plurality of recesses are formed on the side surface of the tip of the optical system,
A bending endoscope characterized in that the head of the bending operation wire is fitted into the recessed part, and the connecting part is fitted and fixed to the distal end of the optical system so as to cover the fitting part. Operation wire locking structure. (2) The recess provided on the side surface of the tip of the optical system expands into a fan shape from the slit at the lower end of the side of the tip of the optical system, so that the head of the bending operation wire extends from the bottom of the neck to the tip. The utility model described in claim (1) is characterized in that the fan-shaped angle of the head is smaller than the fan-shaped angle of the concave portion. Curved operation wire locking structure for endoscopy. (3) The contact surface between the inner surface of the recess and the end surface of the head of the bending operation wire has the same degree of curvature, and the structure is such that the end surface of the head of the bending operation wire can freely slide against the inner surface of the recess. An operation wire locking structure for an endoscope according to claim (1) of the registered utility model, characterized by:
