Title: DISTAL END COVER FOR ENDOSCOPE
Abstract:
A distal end cover 30 for an endoscope is mounted on a distal end member 20 to which a raising base 40 of an insertion part of an endoscope 1 is provided, said distal end cover 30 covering a part of the distal end member 20, and having an opening 30a through which the space in which the raising base 40 is accommodated is exposed to the outside, said distal end cover 30 comprising: a break guide part 30j that has a cut-in part 30k formed at the distal end-side peripheral edge of the opening 30a and a thin-walled part 30l that extends in the direction of the proximal end, the distal end of said thin-walled part 30l being connected to the cut-in part 30k; and rotation-stopping parts 30h, 30i that suppress rotation of the distal end cover 30 relative to the distal end member 20 by contacting the wall surfaces that protrude upright from within the region of a surface running along the longitudinal axis of the insertion part, the surface being among the outer peripheral surfaces of the distal end member 20.
