おそれがある等の欠点があった。[Problems to be Solved by the Invention] As mentioned above, in the conventional endoscope operation section, a metal support frame was fixed to a synthetic resin case via a metal body with screws. However, all the complex forces applied to the support frame are concentrated on the parts screwed to the case, which tends to cause twisting and deformation of the case. Since the eyepiece part that touches the face was electrically connected via a fixing screw, there was a drawback that the operator could suffer burns due to leakage current when using the high-frequency treatment instrument.
