Claims

[Scope of utility model registration request]

In an endoscope that transmits an optical image of an object through a relay lens system fitted to a lens pipe and uses an image rotator for reversing the optical image on the final stage side of the relay lens system, the lens pipe is concentric with the central axis of the lens pipe. It has a frame fixed in a shape, a threaded part formed on the peripheral surface of the rear end of the frame so as to be concentric with the central axis of the lens pipe, and a presser member having a thread formed on its outer periphery. An endoscope characterized in that the image lochie is pressed and fixed from the front and back in the direction of the central axis of the lens pipe by screwing together a presser member at the notch.
