PROBLEM TO BE SOLVED: To provide a means for reducing the weight of a seedling stand and a transplanter. SOLUTION: The seedling planting device puts a seedling on a seedling placing portion 13a and reciprocates in a lateral direction of the machine body, and a seedling take-out port 13d for the seedling placed on the seedling placing base 13. And a seedling vertical feeding device 21 for vertically feeding the seedlings, a seedling planting mechanism for planting in the field from the seedling take-out port 13d, and a seedling placing portion 13a. The seedling stay 30 for suppressing the floating of the seedlings, and the resin lower support portion 50 for supporting the lower end portion of the seedling stay 30 on the seedling placing table 13 are provided. [Selection diagram] Figure 2【課題】苗載せ台及び移植機の重量を軽減する手段を提供する。【解決手段】苗植付け装置は、苗載置部１３ａに苗を載置して機体横方向に往復移動される苗載せ台１３と、苗載せ台１３に載置された苗を苗取り出し口１３ｄに向けて縦送りする苗縦送り装置２１と、苗取り出し口１３ｄから圃場へ植え付ける苗植え付け機構と、苗載置部１３ａの苗のせ面に対向して配置され、苗載置部１３ａに載置されている苗の浮き上がりを抑制する苗ステー３０と、苗ステー３０の下端部を苗載せ台１３に支持させる樹脂製の下側支持部５０と、を備える。【選択図】図２
