とを特徴とする内視鏡の湾曲操作装置。[Claims for Utility Model Registration] A bendable curved portion provided between the distal end portion and the flexible tube, and a circular portion rotatably provided on the operating portion connected to the other end of the flexible tube. A pulley having a circumferential groove formed therein, and an operating wire having one end attached to the tip of the curved part and the other end wound around the groove of the pulley, and by rotating the pulley. In the bending operation device for an endoscope, the bending operation device for an endoscope is configured to bend the bending portion by pulling the operation wire, and a groove formed in the pulley is inserted into the pulley at a portion opposite to the pulling direction of the operation wire. 1. A bending operation device for an endoscope, characterized in that the notch is deeply cut out so that the slack generated in the loose side operation wire is absorbed within the cutout.
