The four vertical frame members 61A to 61D are arranged on both sides in the travel direction and the transfer direction of the stacker crane 11, and extend in the vertical direction. The transfer-direction frame members 63A to 63D extend in the transfer direction, and connect respective upper sections and respective lower sections of the vertical frame members 61A to 61D arranged side by side in the transfer direction. The travel-direction frame members 65A to 65D extend in the travel direction, and connect the vertical frame members 61A to 61D arranged side by side in the travel direction. The slanting member 67A connects intersection points between the vertical frame members 61A, 61B and the transfer-direction frame members 63A, 63B, and extends in a slanting direction.
