In this case, since the movable support 34 is provided on the rotatable arm 33, it does not break the seedling containers 2 piled up and down while contacting with the lower surface of the second stage seedling container 2 from the bottom while rotating upward. It does not interfere with the transfer of the preceding seedling raising container 2.

Further, since the front and rear ends of the chain guide rail 36 are bent downward, the impact when the movable support 34 hits the lower surface of the seedling growing container 2 is preferably reduced.
The chain guide rail 36 is provided between the gear 23 and the gear 24, but the guide roller 35 of the arm 33 is placed on the roller receiving portion 37 at least in front of the front-rear middle position, and the lowermost seedling growing container The moving support 34 may support the seedling raising container 2 until the rear end of the second seedling passes below the front end of the second stage raising seedling container 2 from below. The stopper 15 and the second-stage support roller 20 support the rear end of the second-stage seedling raising container 2 from the bottom when the front end of the second-stage seedling raising container 2 comes into contact with the stopper 15. Since the roller 20 is disposed so as to be placed on the upper surface on the rotating lower side in front of the apex of the roller 20, the moving support member 28 immediately behind the transfer member 26 for transferring the lowermost seedling raising container 2 is the second-stage seedling raising container from the bottom. After passing the second front end, the front end of the second-stage seedling raising container 2 from the bottom descends to make room for the stopper 15, and at the same time, the rear end of the second-stage seedling raising container 2 from the bottom is the second-stage support roller. 2
