Abstract

PURPOSE: To surely engage a tip cover of a sheath to the tip of an inserting part of an endoscope, and also, to easily detach it by providing an engaging means for deforming elastically the tip cover to the inside from the outside toward a space, and detaching it from the tip part body.
CONSTITUTION: The tube body 21 of a sheath covered so as to be insertable/ detachable into/from an inserting part from the tip side is formed in a thin cylindrical shape, for instance, a flexible raw material such as silicone rubber. To the tip of the tube body 21, the tip cover 22 of a transparent synthetic resin covered so as to be insertable/detachable into/from a tip part body 13 is connected watertightly. The tip cover 22 of the sheath is formed in a cylindrical shape, therefore, between a slant face 19 of the tip part body and the tip cover 22, a space 18 is formed. When an endoscope inspection is ended, the tip cover 22 is pinched with fingers toward the space 18 part from both left and right sides, and deformed elastically so as to be longitudinal. When the tip cover 22 is deformed elastically so as to be longitudinal respective chip claws 43, 44 move in the direction for coming out of grooves 41, 42 as indicated with arrows B, C, and their engagement can be released.
