PROBLEM TO BE SOLVED: To provide a shelf for storing a seedling box, surely maintaining the shape in a plan view by preventing deformation of vertical crosspieces forming an outer frame in a simple construction, smoothing the work for putting the seedling box in and out from a shelf portion, and simply and surely maintaining the shape in a plan view of the vertical crosspieces after assembling even when the vertical crosspieces, horizontal bars and vanes are unitized.SOLUTION: This shelf includes: vertical crosspieces respectively erected in the vertical state at four corners of a square at least in a plan view a horizontal crosspiece whose ends are fixed to the opposite surfaces of the vertical crosspieces in the front and rear direction being the direction of taking out and putting in the seedling box connecting members respectively connecting the upper and lower end parts of the crosspieces to each other in the lateral width direction orthogonal to the front and rear direction among the vertical crosspieces long vanes respectively fixed to the opposite surface sides in the lateral width direction of the vertical crosspiece or the horizontal crosspiece to form a shelf portion where both end parts of the bottom surface of the seedling box can be placed and a reinforcing member for connecting the upper end parts of at least one pair of vertical crosspieces located on a substantially diagonal line among the crosspieces.COPYRIGHT: (C)2013,JPO&INPIT【課題】簡易な構成により外枠を形成する縦桟の変形を防止して平面視形状を確実に維持でき、棚部内への苗箱の出し入作業をスムーズに行い得たり、縦桟と横桟及び翼板がユニット化される場合であっても、組み立て後の縦桟の平面視形状を簡単かつ確実に維持し得る苗箱収納棚を提供する。【解決手段】少なくとも平面視で方形状の四隅に垂直状態でそれぞれ立設された縦桟と、該縦桟の苗箱の出し入れ方向である前後方向の対向面にその端部が固定された横桟と、縦桟のうち前後方向と直交する左右幅方向の縦桟の上下端部をそれぞれ連結する連結部材と、縦桟及びまたは横桟の左右幅方向の対向面側にそれぞれ固定されて苗箱の底面両端部が載置可能な棚部を形成する長尺状の翼板と、縦桟のうち略対角線上に位置する少なくとも一対の縦桟の上端部分を連結する補強部材と、を備えることを特徴とする。【選択図】 図1
