Abstract

Abstract An anchoring structure for an endoscope cover comprising a cylindrical rigid cover (6) composed of an elastic material, which is fitted to an endoscope to cover a top end rigid portion (5) of the endoscope. A transparent window (6b, 6c) arranged on a closed face formed on the top end of the rigid cover to confront at least an observation port and an illuminating port, which are arranged on the top and of the endoscope, and a bag-shaped covering member (7) having a length covering at least an intermediate conduit portion of the endoscope, which is attached to the rear part of the endoscope. An anchoring concave portion (3b) is formed at a predetermined part of the intermediate conduit portion (3), a notched face (5a, 5b) is formed on the circumferential face of the top end rigid portion and an anchoring groove (5c) is formed on the circumferential face. Anchoring projections (6d, 6e) are formed at confronting position on the inner circumferential face of the rigid cover (6) and the anchoring projections are fitted in the anchoring groove (5c) of the top end rigid portion to make it possible to fix the rigid cover to the top 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.
