PROBLEM TO BE SOLVED: To easily achieve insertion of an endoscopic fiber that has conventionally been difficult by composing it so as to automatically advance to the depth of an intestinal tract instead of requiring a manual procedure, and make it possible to be inserted into the depth of the small intestine. SOLUTION: Oar-like artificial muscles which act like oars from outward and forward to inward and backward are radially installed at the front and the back on the outside of a cylindrical artificial muscle which is expansible forward and backward to be installed and fixed on the outside of the endoscopic fiber around the longer axis of the endoscopic fiber as the center axis so as to make it possible to advance the endoscope. The automatic endoscope inserting device can be kept clean inside by being covered by an elastic cover therearound. The number or shape of the oar-like artificial muscles installed at the front and the back may be varied. COPYRIGHT: (C)2009,JPO&INPIT
