A transport device includes a large-article drive portion that moves each of a pair of large-article supporting portions between a large-article supporting position and a large-article retracted position, and a small-article drive portion that moves each of a pair of small-article supporting portions between a small-article supporting position and a small-article retracted position. The small-article retracted position is set at a height at which the pair of small-article supporting portions are located above a supported portion supported by the pair of large-article supporting portions, and the pair of small-article supporting portions are provided between the pair of large-article supporting portions in a lateral width direction.
