PROBLEM TO BE SOLVED: To provide a container intended for facilitating loading and unloading raising seedling boxes on frames on a load-carrying platform of a truck when carrying to a field by a truck, through using frames which support raising seedling boxes in an inclinedly standing posture and arrange many raising seedling boxes in a line to install.SOLUTION: This container comprises assembling in a ladder-like state, frames on which raising seedling boxes are arranged in a line and laid in an inclinedly standing posture, with right and left side frames of a length almost corresponding with a front and back length or a right and left width of a load-carrying platform of a truck, and raising seedling box supporting frames to be bridged between the side frames, and setting rails along the longitudinal direction on the frames, and separately forming a base stand of a width almost corresponding with a floor of the load-carrying platform of a truck followed by laying across on the upper surface of the load-carrying platform of a truck in a manner capable of pulling down. Furthermore, the container comprises setting on the base stand, rails engageable with the rails which are set on each of the frames in a condition of arranging the frames in a line and loading, on a position corresponding to the rails, and laying across the frames arranged in many lines, in a freely drawing manner from the load-carrying platform of a truck by engaging the rails with the rails of the frames.COPYRIGHT: (C)2009,JPO&INPIT【課題】育苗箱を、斜めに起立した姿勢に支持せしめて、多数枚並列させて支架する架台を用いて、運搬車により圃場に運搬するときの、運搬車の荷台上の架台に対する育苗箱の積み込みと、荷降ろしとが楽に行えるようにする。【解決手段】育苗箱が斜めに起立する姿勢で並列装架される架台を、運搬車の荷台の前後の長さまたは左右の巾に略対応する長さの左右の側枠と、それら側枠間に渡架する育苗箱の支持枠とで、はしご状に組み立て、その架台に長手方向に沿う軌条を装設し、別に、運搬車の架台の床面に略対応する広さの基台を形成して、運搬車の荷台の上面に取り下ろし可能に装架し、その基台には、前記架台を並列させて載架した状態において各架台に装設せる軌条と対応する位置に、その軌条に嵌り合う軌道を形設し、この軌道と前記架台の軌条との嵌合により、多連に並列せる架台を、運搬車の荷台に対し引き出し自在に装架せしめる。【選択図】図5
