PROBLEM TO BE SOLVED: To allow articles to be stably stacked in multiple stages by forming an upper face fitting protrusion protruding upward on an upper face of a hill formed on a mount board and by concaving a bottom of a recess or a stage to form a lower fitting part protruding from a lower face of the mount board. SOLUTION: An upper fitting protrusion (m) is provided to protrude upwardly from an upper face of an outer hill formed adjacent to a rim of a mount board 1. In addition, a bottom 3' of an annular recess is concaved downward to form a lower face fitting protrusion (d) protruding downwardly from a lower face of the mount board 1. When the transfer tray T is put over a pallet, side walls 2 hanging downwardly from four side rims of the mount board 1 are positioned close to side faces of the pallet, as well as the lower fitting protrusion (d) is fitted into a through hole formed on an upper deck board. This limits horizontal movement of the transfer tray T with respect to the pallet, thereby improving stability of articles stacked in multiple stages via the transfer trays T. |
