  • the coupling member may be more stably fixed.
  • Edge frames and a corner connection portion for connecting the edge frames are used at an edge of the pallet body portion, thereby preventing an edge portion of a pallet from breaking due to collision, etc.
  • An accommodation groove may be formed in an outer edge and a lower edge of a box may be inserted into the accommodation groove to allow the box to be more stably positioned on the pallet.
  • corner connection portion may connect edge frames that cross each other to achieve entire structural stability of an outer frame and to enhance impact resistance.
  • a supporting leg support may be arranged on an upper surface of the cover member and, thus, when box assemblies for delivery are arranged as a multilayer structure, a more stable state may be maintained.
  • a coupling member for coupling a supporting leg support of a cover member may not be externally exposed and, thus, interference between the coupling member and goods in the box may be completely prevented.
  • Edge frames and a corner connection portion for connecting the edge frames may be used at an edge of a cover body portion and, thus, a problem in that an outer portion of the cover member breaks due to collision, etc. may be overcome.
  • An accommodation groove may be formed in an outer edge and an edge of an upper surface of a box may be inserted into the accommodation groove to stably position the cover member in the box.
  • a corner connection portion may connect edge frames that cross each other to achieve entire structural stability of an outer frame and to enhance impact resistance.
