Abstract
An endoscope cover comprising a cylindrical end rigid cover portion composed a flexible material, which is fitted to an endoscope to cover a distal end rigid portion of the endoscope. A transparent window arranged on a closed face formed on the distal end of the rigid cover to confront at least an observation port and an illuminating port, which are arranged on the distal end of the endoscope, and a bag-shaped covering member having a length covering at least an intermediate conduit portion of the endoscope, which is attached to the rear part of the endoscope. A groove or notched face is formed in the longitudinal direction of the outer periphery of the distal end rigid portion of the endoscope and an anchoring groove is formed on the circumferential face portion. Anchoring projections are formed at confronting positions on the inner circumferential face of the rigid cover and are fitted in the anchoring groove formed in the distal end rigid portion to attach the rigid cover to the top end rigid portion. The covering member is bonded to all or a part of the periphery of the intermediate conduit portion by using an adhesive.
