ことを特徴とする内視鏡における鉗子等の導入装置。A closing member made of an elastic material that closes the open free end side on the insertion side of a treatment instrument such as forceps for forming the proximal end of the introduction channel for a treatment instrument such as forceps, which is installed in the operation section main body of the endoscope. It consists of a columnar main body part whose outer wall surface has a considerable distance from the inner wall surface of the mouthpiece for inserting a treatment instrument such as forceps, and a flange-like base part provided on the insertion side of the treatment instrument such as forceps of this columnar main body part. On the insertion side of the treatment instrument such as forceps, a concave hole with a tapered conical shape is formed so that the axis coincides with the axis of the columnar body, and the columnar body is divided along the axis. ``A columnar closure member made of an elastic material is formed with a divided surface that fits tightly, and an elastic covering tube is fitted around the outer periphery of the columnar closure member made of an elastic material to urge the divided surface to be brought into close contact. An introduction device for forceps or the like in an endoscope, characterized in that:
