Claims

[Scope of utility model registration request]

In an endoscope bending operation device that bends the insertion section of an endoscope by pushing and pulling an operating wire, a single hook is formed on a pulley body with a groove formed on the circumference, and on one side wall of the pulley body. A protrusion is formed to hook the intermediate portion of the operating wire, and a notch groove is cut out at one location of the peripheral wall of the side wall where the protrusion is provided and communicates from the side wall to the groove. A bending operation device for an endoscope, characterized in that an intermediate portion of the operating wire is hung on the protrusion, and both ends of the operating wire are passed through the notched groove and the hook is guided into the groove.
