DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A plant factory 1 according to a preferred embodiment will be described below with reference to FIGS. The plant factory 1 includes a greenhouse 2. The inside of the greenhouse 2 is partitioned by a partition member 7 and divided into a growing area 3 and a work area 5. Air conditioners 4 and 6 are installed in the breeding area 3 and the work area 5, respectively. The partitioning member 7 is provided with two automatic doors 9 and an automatic door 11 provided with sensors such as a limit switch having a sliding door structure at two locations. These are normally in a closed state, and are transported while being suspended by an endless transport device 13 which will be described later.
(Not shown in FIG. 1) automatically opens and closes when passing through them, permitting the passage. Further, by dividing the plant factory 1 by the partition member 7, the humidity of the growing area 3 and the humidity of the work area 5 can be made different. This is because humans and plants have different preferred environments. Since the humidity of the breeding area 3 is appropriately adjusted, there is an advantage that the plant is less likely to be ill. By lowering the humidity of the work area 5, a comfortable work environment can be provided. The same applies to temperature adjustment. An endless transport device 13 penetrates the automatic door 9 and the automatic door 11 and is disposed in the growing area 3 and the work area 5. In the breeding area 3, the endless transporting device 13 has a plurality of meandering portions, and consideration is given to uniformity of sunlight. Note that the partitioning member 7 does not partition the breeding area 3 and the work area 5 but can be configured integrally.

As shown in FIG. 2, the endless transfer device 13 is fixed to the ceiling constituent member 12 in a state of being suspended therefrom. (Horizontal direction), and is characterized in that the cultivation pot 26 (see FIG. 3) is suspended and moved in the horizontal direction. In the breeding area 3 and the work area 5, as shown in FIG. 3, the components of the endless transport device 13 are modularized. The endless transport device 13 includes a horizontal straight rail and a horizontal curved rail, and has a plurality of parallel meandering portions (see FIG. 1).
