An elevator includes: an elevator carriage that moves up and down; a partition that divides a space within the elevator carriage into a first elevator space for a person to board and a second elevator space for an unmanned transport vehicle to board; an elevator rail that includes a movable rail and is arranged in the second elevator space; and an actuator that moves the movable rail. The unmanned transport vehicle travels along the elevator rail, and the movable rail is switched between a first rail state and a second rail state by actuation of an actuator. In the first rail state, the first end of the movable rail is connected to the second end of the story rail, and in the second rail state, the first end is not connected to the second end.
