ABSTRACT:
An anchoring structure for an endoscope cover comprising a cylindrical rigid cover composed of an elastic material, which is fitted to an endoscope to cover a front end rigid portion of the endoscope. A transparent window is arranged on a closed face formed on the front end of the rigid cover to face at least an observation port and an illuminating port, which are arranged on the top end of the endoscope. A bag-shaped covering member having a length covering at least an intermediate conduit portion of the endoscope is attached to a rear part of the endoscope. An anchoring concave portion is formed at a predetermined part of the intermediate conduit portion, a notched face is formed on the circumferential face of the top end rigid portion and an anchoring groove is formed on the circumferential face. Anchoring projections are formed at opposite positions on the inner circumferential face of the rigid cover, and the anchoring projections are fitted in the anchoring groove of the top end rigid portion to make it possible to attach the rigid cover to the front end rigid portion. The covering member is anchored in the anchoring concave portion of the intermediate conduit portion so that the covering member can be integrated with the intermediate conduit portion.
