PROBLEM TO BE SOLVED: To provide a mobile rack facility capable of executing width displacement control of a mobile rack without using a seat rail-like detecting object. SOLUTION: A magnet is provided as the detecting object at a stop position of each mobile rack on a floor surface, and a magnetic sensor detecting the magnet is provided in each mobile rack. When the travelling of the mobile rack 11 is stopped, the magnet is detected by the magnetic sensor, and when detected magnetic sensitivity is varied by a prescribed value or more than that detected at the last stop of travelling, that is, when the width displacement larger than the prescribed value is detected, a travelling track of the mobile rack to solve this width displacement is obtained, and the rotational speed of each driving motor is controlled to accord with the travelling track upon the next travelling.
