It is the easiest for the driver and work assistants to put the spare seedlings in and out of the spare seedling mounting table around the spare seedling mounting table because of the fact that everything is arranged in the same direction in the lateral direction. If I was not in that position, I had to go to that position before taking in and out the spare seedlings.

Therefore, as a technique for improving the above-mentioned points, the support column is configured to be rotatable about its axis so that the preliminary seedling mounting table can be laterally changed to a desired direction. Even if the drivers were not in the position where the spare seedlings could be put in and taken out most easily around the spare seedling mount,
It has been proposed that a spare seedling can be taken in and out at that position [for example, Japanese Patent Application Laid-Open No. 7-115816].

However, according to this structure, since all of the plurality of preliminary seedling mounting bases are arranged in the lateral direction along the same direction, the drivers take out the preliminary seedlings from the preliminary seedling mounting base. Alternatively, when replenishing, the column must be rotated up to 180 °, and in such a case, it took some time for the preliminary seedling stand and the preliminary seedling on it to face in a desired direction.

An object of the present invention is to provide a spare seedling mount and a spare seedling on the spare seedling mount in a desired direction in a shorter time when a driver or a work assistant takes out or supplies the spare seedling from the spare seedling mount. It is to improve workability by making it possible to move to.
