っていた。However, if the rigidity of the spring wire is increased in order to enhance the seedling support function, the seedling support rods become elastically deformed (which causes the planting claws and the seedling support rods themselves to be easily damaged or deformed; By making the support rods flexible so that they can easily swing elastically in the width direction along the seedling placement surface to reliably prevent the above-mentioned damage, it is possible to prevent the mat-shaped seedlings from shifting laterally due to friction with the sliding rail. This makes it difficult to set the rigidity of the spring wire.Furthermore, the seedling support function tends to change due to assembly errors and manufacturing errors of the seedling support rod, and it is difficult to set the rigidity of the spring wire. It has become difficult to stabilize the performance of
