PROBLEM TO BE SOLVED: To provide a seedling box storage shelf in which a reinforcement crosspiece is arranged so that its position can be adjusted, between facing lower lateral crosspieces, framework intensity can be enhanced sufficiently even when a storage shelf is large, and which can be stably mounted on a loading space of a light truck.SOLUTION: A seedling box storage shelf comprises left and right upper lateral crosspieces and lower lateral crosspieces, plural vertical crosspieces in a cross direction which are respectively vertically arranged between the upper and lower lateral crosspieces, and plural blade plates which are arranged between a facing surface of the pair of vertical crosspieces facing in the lateral direction with a prescribed gap, and between connection parts between four corner parts of the left and right lower lateral crosspieces and the vertical crosspieces, a reinforcement crosspiece is arranged, a position of the reinforcement crosspiece can be adjusted to a cross direction orthogonal to the lateral direction and the reinforcement crosspiece can contact a loading space of the light truck. The reinforcement crosspiece comprises a body pipe whose both ends are open, reinforcement blocks which are fitted and fixed to both openings of the body pipe, and an attachment pipe which is fixed to an inner wall face in the vicinity of the connection part of the lower lateral crosspiece and to which the other end part of the reinforcement block is detachably fixed and fitted.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】対向する下横桟間に補強桟を位置調整可能に配設して、大型の収納棚であっても枠組み強度を十分に高めつつ軽トラックの荷台に安定搭載できる苗箱収納棚を提供する。【解決手段】左右の上横桟及び下横桟と、上横桟と下横桟間に垂直状態でそれぞれ配設される前後方向の複数の縦桟と、左右方向に対向する一対の縦桟の対向面間に所定の間隔を有して上下方向に配設される複数の翼板とを備え、左右の下横桟四隅の縦桟との連結部間に、左右方向と直交する前後方向に位置調整可能で軽トラックの荷台に当接可能な補強桟が配設されていることを特徴とする。前記補強桟は、両端が開口した本体パイプと、本体パイプの両端開口に嵌合固定される補強用ブロックと、下横桟の連結部近傍の内壁面に固定され補強用ブロックの他端部が着脱可能に嵌合固定される取付パイプを有する。【選択図】 図2
