PROBLEM TO BE SOLVED: To provide a holder for holding a seed bulb in a transplanter, capable of freely changing the transplanting interval, and transplanting the seed bulb while keeping the proper direction without damaging the seed bulb.SOLUTION: The holder 78 for holding the seed bulb in the transplanter for carrying out the transplantation of the seed bulbs at a prescribed interval while traveling on a field is equipped with a holding plate 178 constituted of an elastomer and having a plurality of slits 78b radial from the center to the out side, and a perforated board 179 having an opening having a radius equal to that of the slits 78b at the center. Pluralities of the holding plates 178 and the perforated boards 179 are installed by being alternately piled while making the centers thereof coincide. The holding plate 178 is piled so that the directions of the slits 78b may coincide with those of other holding plates 178, 178, 178 in plane view.COPYRIGHT: (C)2010,JPO&INPIT【課題】自由に植付間隔を変更できるとともに、種球を傷つけることなく適正な向きを保持して植付できる植付機の種球保持用ホルダを提供する。【解決手段】圃場に走行しながら所定間隔をおいて種球の植付けを行う植付機の種球を保持するホルダであって、前記ホルダ78は、弾性体で構成して中央から外方へ放射線状に複数の切れ目78bを備える保持板178と、中央に前記切れ目78bと同半径の開孔を有する開孔板179とを有し、前記保持板178と前記開孔板179とを中心を一致させて交互に複数重ね合せて貼設する。前記保持板178は、他の保持板178・178・178とそれぞれ平面視において前記切れ目78bの方向を一致するように重ね合せる。【選択図】図6
