特徴とする硬性内視鏡。[Scope of Claim for Utility Model Registration] An optical tube in which an illumination optical system and an observation optical system are inserted into a rigid ultra-thin pipe, an eyepiece with a built-in eyepiece, and a main body in which these optical tubes and eyepiece are connected. In the rigid endoscope, a hole is formed at the distal end of the main body, and the optical tube is supported through the hole, while the side wall on the distal end side of the hole is set to a limit at which bending occurs in the optical tube. A rigid endoscope, characterized in that it is expanded with a curved line having a smaller curvature than the curvature of the rigid endoscope.
