PROBLEM TO BE SOLVED: To improve the sliding durability and maintenance of a seedling stand and improve operability in switching the seedling stand from its working mode to housing mode.SOLUTION: A seedling stand division structure for rice transplanters is provided, being such that: a seedling stand 15 is made switchable between working mode and housing mode through displacement of the seedling stands 15B divided from the main seedling stand 15A there are provided guide mechanisms 24 and 25 guiding right and left the seedling stand 15 in between a supporting frame 20 and the seedling stand 15 in such a condition as to block the displacement of the seedling stand 15 in the direction of crossing seedling standing surface these guide mechanisms 24 and 25 are provided with a plurality of rotators 28, 32 set on the supporting frame 20 in a state of being arranged right and left and grooves 26a, 29a allowing the relative movement relative to the rotators 28, 32 right and left and engaging with the rotators 28, 32 so as to block the relative displacement in the direction of seedling stand surface crossing, and there are equipped with engagement members 26, 29 equipped with the seedling stand 15, and a displacement-allowing part 81 allowing the displacement of the seedling stands 15B in the direction of seedling stand surface crossing.COPYRIGHT: (C)2014,JPO&INPIT【課題】苗載台の摺動に関する耐久性及びメンテナンス性の向上とともに、苗載台を作業状態から収納状態に切り換える際の操作性の向上を図れるようにする。【解決手段】苗載台15を、主苗載部15Aから分割した分割苗載部15Bの苗載面交差方向への変位で作業状態と収納状態とに切り換え可能にし、支持フレーム20と苗載台15との間に、苗載台15の苗載面交差方向への変位を阻止した状態で苗載台15を左右に案内するガイド機構24,25を備え、ガイド機構24,25に、支持フレーム20に左右方向に並べた状態で配備する複数の回転体28,32、回転体28,32との左右方向への相対移動を許容し、かつ、苗載面交差方向への相対変位を阻止するように回転体28,32に係合する係合溝26a,29aを備えて苗載台15に装備する係合部材26,29、分割苗載部15Bの苗載面交差方向への変位を許容する変位許容部81を装備した。【選択図】図6
