In order to fold the seed-separated seedling mounting table compactly, for example, cam means provided between the rotating frame and the seedling mounting base body and between the rotating frame and the divided seedling mounting table are used. In addition, the divided seedling mounting table is moved upward in conjunction with the folding operation of the divided seedling mounting table so as to avoid interference with a seedling stand shoe or a guide fixed to the main body side. However, in such a configuration means that the upward movement is performed in conjunction with the folding operation of the divided seedling mounting table, the upward movement amount is small immediately after the start of folding, and therefore, it is fixed to the back side of the divided seedling mounting side. There has been a problem that the fitting between the upper and lower guide rails, the seedling stand shoe and the guide body on the main body side cannot be completely released.
