<P>PROBLEM TO BE SOLVED: To provide a planting tray capable of achieving the improvement or the like of a transportation efficiency, and to provide a stepwise piled structure thereof. <P>SOLUTION: The planting tray 1 is equipped with a bottom wall-constituting part 2, and an outer periphery wall 3 extended upward from the outer perimeter of the bottom wall-constituting part 2. First supporting parts 41a for supporting the lower parts (fitting parts 53) of girder-receiving parts 51 constituted as separated bodies from the planting tray 1, and second supporting parts 41b installed just under the first supporting parts 41a and supported by the upper parts (receiving wall parts 62 and positioning parts 54) of the girder-receiving parts 51 are installed at the four corners of the planting tray 1. The planting trays 1 are piled stepwise by allowing the lower parts of the girder-receiving parts 51 to be supported by the first supporting parts 41a of the planting tray 1 respectively, and the second supporting parts 41b of the different planting tray 1 to be supported by the upper parts of a plurality of the girder-receiving parts 51 the lower parts of which are supported by the planting tray 1 respectively. <P>COPYRIGHT: (C)2011,JPO&INPIT |
