PROBLEM TO BE SOLVED: To provide a transplanter which allows the easy attachment of an extruder shaft by facilitating fine adjustment movement in a vertical direction by freely fastening a nut by one hand while keeping a seedling extruder held at a rod in a proper extrusion position by another hand.SOLUTION: A cylindrical shaft shaped attachment shaft part 15c having a rod shaft hole 27 which allows insertion of an extruder shaft 23 arranged at an upper part of a seedling extruder 12 from a lower end in a loosened state is arranged at a lower part of a rod 15, the attachment shaft part 15c is formed into a tapered external peripheral face which sequentially has different diameters in the axial direction, a screw part 29 which allows screw penetration of a nut 25 is formed, slits 30 which are notched in the axial direction from a lower end of the attachment shaft part 15c are formed in the circumferential direction at prescribed intervals, and a plurality of attachment pieces 31 which have elastic forces toward the lower end side from a shaft upper side, and are displaceable in the axial core direction are formed.COPYRIGHT: (C)2015,JPO&INPIT【課題】苗押出具をロッドに適正押出位置に保持したまま他方の手でナットを締付け自在にすることにより、押出具軸を上下方向への微調整移動を容易にして取付けることができる移植装置を提供する。【解決手段】ロッド15の下部に、苗押出具12の上部に設けた押出具軸23を下端から遊嵌状態で挿入させるロッド軸穴27を有する筒軸状の取付軸部15cを設け、該取付軸部15cを軸方向に順次異径をなすテーパー状の外周面となしてナット25を螺挿させるネジ部29を形成すると共に、取付軸部15cの下端から軸方向に切欠するスリット30を周方向に所定間隔を有して形成し、軸上部側から下端側に向けて弾性力を有して軸芯方向に変位可能な複数の取付片31を形成した。【選択図】図6
