To provide a seedling transplanter improving accuracy of a scraping position of a seedling mat by a planting claw by suppressing positional deviation of the seedling mat with respect to a guide rail.SOLUTION: A seedling transplanter for cutting out a seedling mat 100 part by part by a planting claw to continuously plant seedlings in a field, includes a guide rail 48 provided on a lower side of a seedling tray, extending in a horizontal direction of a transplanter body, supporting the seedling mat 100 by receiving contact of an end face part 100b on a lower side of the seedling mat 100 so as to regulate a position of the seedling mat 100 with respect to a trajectory of the planting claw. The guide rail 48 includes a contact support face part 130 for receiving the contact of the end face part 100b on the lower side of the seedling mat 100, and a groove forming part 133 for forming a recessed groove 131 in the contact support face part 130 and forming a space 132 toward the end face part 100b on the lower side of the seedling mat 100, where the contact support face part 130 has a shape along the groove forming face 103a that forms a surface-side groove part 103 of the seedling mat 100.SELECTED DRAWING: Figure 16 【課題】苗移植機において、ガイドレールに対する苗マットの位置ずれを抑制することを可能とし、植付爪による苗マットの掻取り位置の正確性を向上する。【解決手段】植付爪によって苗マット１００を一部ずつ切り取って連続的に苗を圃場に植え付けていく苗移植機であって、苗載台の下側に設けられ、機体の左右方向に延伸し、苗マット１００の下側の端面部１００ｂの接触を受けて苗マット１００を支持することで、植付爪の軌道に対して苗マット１００の位置を規定するガイドレール４８を備え、ガイドレール４８は、苗マット１００の下側の端面部１００ｂの接触を受ける接触支持面部１３０と、接触支持面部１３０に対して凹状溝１３１を形成し苗マット１００の下側の端面部１００ｂとの間に空間１３２をなす溝形成部１３３と、を有し、接触支持面部１３０は、苗マット１００の表面側溝部１０３を形成する溝形成面１０３ａに沿う形状を有する。【選択図】図１６
