置。1. A pulling wire for bending operation is wound around and fixed to each pulley connected to the left and right angle knobs and the upper and lower angle knobs of the endoscope operation section, and each angle knob is rotated to rotate the inside. In an endoscope bending operation device that bends a bending portion of a distal end of an endoscope in a desired direction, a recess is formed in an outer peripheral portion of the pulley around which the pulling wire is wound, and the pulling is performed in the recess. A tubular member having a wire through hole formed therein is inserted from a direction orthogonal to the winding direction of the pulling wire, and the fixing member is inserted from an opening formed in a side portion of the endoscope hand operation portion corresponding to the recess. Is inserted into the tubular member and the pulling wire is fixed to the tubular member, whereby the pulling wire is fixed to the pulley.
