UNMANNED CARRIER

PROBLEM TO BE SOLVED: To provide an unmanned carrier which suppresses the damage of guide tapes, reduces the number of guide sensors, achieves the simplification of a device configuration and the easiness of assembly, and improves safety in traveling. SOLUTION: The unmanned carrier includes: a traveling truck for mounting a cylindrical workpiece; four caster wheels for supporting the traveling truck on a traveling road surface so as to freely travel back and forth and right and left; two driving wheels for applying driving force to the traveling truck; and a plurality of guide sensors for detecting guide tapes for forward and backward traveling, a guide tape for horizontal traveling and a stop marker on the traveling road surface. In the unmanned carrier, the guide sensors include forward/backward traveling guide sensors each of which is arranged on each of the front side and the rear side on a center line of a longitudinal direction and one or two horizontal traveling guide sensors arranged in the center line of a minor-side direction, and each of the guide sensors includes a guide sensing function for detecting a traveling direction and a stop sensing function for detecting a stop position.
