To provide an automatic guided vehicle turning to the right and left turning ends with simple constitution to search a guide line.
Stopper members stop turning of a drive unit by contacting each other at the right and left turning ends of a turning unit to a machine base. A microcomputer 75 controls motors 35, 37 when the guide line cannot be detected by a guide line detector 31, to rotate one of right and left driving wheels normally while rotating the other reversely to turn the drive unit. The microcomputer 75 determines arrival at the turning end when at least one of the rotating speeds of the right and left driving wheels during turning of the drive unit is reduced, and rotates the right and left driving wheels in an opposite direction to a rotating direction up to that time to turn the drive unit in an opposite direction to the turning direction up to that time.
