Abstract:
A fire protection door in an open position is present above a traveling path of a transport vehicle. The fire protection door is capable of moving downward from the open position to a closed position along a door trajectory. The transport vehicle includes: a control portion; an area detection portion that detects an interference area, which is an area in which a portion of the transport vehicle in the traveling path overlaps the door trajectory; and a descent detection portion that detects a descent of the fire protection door. The control portion performs a retraction control such that the transport vehicle travels to the outside of the interference area when the descent detection portion has detected a descent of the fire protection door in a state in which the transport vehicle is located in the interference area.
