PROBLEM TO BE SOLVED: To provide a seedling transplanter in which transmission of driving force to seedling planting unit is stabilized even in a field where operating condition and soil condition of the field tend to vary, and which can prevent fluctuation of planting posture of seedlings and defective planting of the seedlings by suppressing variation of loads and resistance.SOLUTION: In the seedling transplanter, a seedling planting unit 2 is upward/downward movably connected to a rear part of a vehicle body 1 via a lift link 3, and a part from a PTO shaft 4 at the vehicle body 1 side through a planting clutch 5, universal joint 6, and an interlocking shaft 7 to a seedling planting mission case 8 side is interlocked. An upward/downward bent angle with respect to a linear interlocking position of the universal joint 6 is set so that a descended angle α at the most descended position of the seedling planting unit 2 and an ascended angle β at a most ascended position is almost the same.COPYRIGHT: (C)2014,JPO&INPIT【課題】走行条件や、圃場の土壌条件が変化しやすい圃場であっても、苗植付部への駆動力の伝動が安定し、負荷や抵抗の変動が抑えられて苗の植付姿勢の乱れや苗の植付損ないが防止できる苗移植機を提供する。【解決手段】車体1の後部に苗植付部2をリフトリンク3を介して昇降可能に連結し、該車体1側のPTO軸4から植付クラッチ5、自在継手6及び連動軸7を経て苗植付部2の苗植伝動ケース8部側へ連動する苗植機において、自在継手6の直線状連動位置に対する上下折れ角を、植付装置2の最下降位置の下降角度αと最上昇位置の上昇角度βとを略等角に設定して構成する。【選択図】図3
