2. Description of the Related Art Conventionally, as a stadium equipped with spectator seats for watching a game such as baseball, soccer, rugby, or tennis, there is a ground (pitch) planted with natural grass. Natural turf in such a field generally needs to grow well under appropriate conditions with well-balanced elements of temperature, light, water, nutrients (fertilizer), air, and soil. By the way, in a multipurpose arena having a natural turf field, there is a risk that the natural turf will be damaged if it is used for purposes other than the above-mentioned competitions.

Therefore, there is known a facility that moves the natural turf field to the outside of the arena to secure sunlight and grow the turf (see, for example, Patent Literatures 1 and 2). In patent documents 1 and 2, when a competition is not held in the arena, the natural turf field is transported in its entirety or in a divided state to an outdoor turf growing space outside the arena, and in the turf growing space under natural light. It describes how to grow in In this case, it is possible to use the arena for other purposes without setting up the natural grass field.
