The object is to provide an article storage facility in which the facility can be downsized by minimizing the width of the travel path for a pair of stacker cranes, in which its configuration is simplified as much as possible, and in which its throughput can be efficiently improved. The control device is configured to perform a mutual avoidance vertical movement process in which both of the pair of vertically movable bodies (UD) are raised or lowered by a vertical movement operation for avoiding interference, which is different from the vertical movement operation in the article transporting operation to raise and lower the pair of vertically movable bodies, to the vertical positions for passing each other which are spaced apart in the vertical movement direction by a distance greater than or equal to the required separating distance which is defined as a separating distance which allows the pair of stacker cranes (3a, 3b) to pass each other without interfering with each other.
