Patent ID: 8038604

Claim:
An endoscope distal end cover, comprising: a cover portion provided with a coupling port, for covering at least a part of an outer circumferential portion of a distal end portion main body configuring an insertion portion of an endoscope; an opening portion for allowing a surface of the distal end portion main body to be in communication with an environment outside of the distal end portion when the cover portion is disposed on the distal end portion main body, the opening portion being formed on the cover portion, the opening portion located away from an edge portion of the coupling port by a predetermined distance; a finger-hooking portion which is a part of the opening portion formed on the cover portion and which is a grasping portion located away from the edge portion of the coupling port by a predetermined distance; a plastic-deformation portion formed adjacent to the finger-hooking portion including a thin-walled portion having a smaller thickness than the thickness of the cover portion on a side surface between the finger-hooking portion and the coupling port in a direction perpendicular to an insertion axis direction of the cover portion, and a concave groove that extends from adjacent the finger-hooking portion, to an opposite side of the cover portion around the periphery of the cover portion, and having first sections along the insertion axis direction and a second section continuous with the first sections in the direction perpendicular to the insertion axis direction, the plastic deformation portion being torn from a position that is away from the edge portion of the coupling port by a predetermined distance by applying force to the finger-hooking portion; and a convex portion engaged with an engaging portion provided to the distal end portion main body, the convex portion being provided on an inner surface of the cover portion adjacent to the plastic-deformation portion.
