PROBLEM TO BE SOLVED: To solve the problem that precision of travel control is limited because of magnetic spread or the like, while a conventional trackless unmanned conveying vehicle traveling along a prescribed travel route on a floor face is guided using a magnetic tape or the like. SOLUTION: This unmanned conveying vehicle is provided with an imaging means for imaging optical marks adjacently provided along the travel route, and a travel position detecting means for confirming a relation between each optical mark and the optical mark as a reference, and for detecting a current travel position of a vehicular body, based on a position on an image of the optical mark whose positional relation included in the up-to-date image is confirmed, and controls traveling of the vehicular body, based on at least an instructed travel position set with respect to the optical mark along the prescribed travel route, out of the optical marks whose positional relation with respect to the optical mark as the reference is determined, and the current travel position of a vehicular body detected by the travel position detecting means.
