An autonomous travel cart includes a control device controlling the autonomous travel cart to travel autonomously based on detection information from an obstacle detection device. The control device includes a wall length detection unit that detects wall lengths of wall portions from the autonomous travel cart to an exit end of the narrow path, a wall length determination unit that determines whether or not the wall lengths are greater than a predetermined wall length threshold, and a narrow path travel control unit that controls the autonomous travel cart to travel at a normal speed when the wall lengths are greater than the predetermined wall length threshold, and to decelerate and travel at a predetermined reduced speed when at least one of the wall lengths detected by the wall length detection unit is equal to or less than the predetermined wall length threshold.
