<P>PROBLEM TO BE SOLVED: To provide a pallet forming member capable of suppressing lowering of rigidity of a beam wall extended from the end surface of a board. <P>SOLUTION: An upper length side middle beam 21A has an end surface wall 1AN extended from the end surface 20E of a deck board 20. A plurality of ribs within beams are constituted of a plurality of parallel ribs 1ARx extended in a direction parallel to the end surface wall 1AN and orthogonal ribs 1ARy extended in a direction perpendicular to the end surface wall 1AN. A gas pressure-injection part 1AP is separated from the end surface wall 1AN more than the parallel rib 1ARx closest to the end surface wall 1AN. The gas pressure-injection part 1AP is connected to the edge surface wall 1AN by paths comprising the plurality of ribs within beams. The shortest path SCA among the paths is composed of the parallel ribs 1ARx and the vertical ribs 1ARy which intersect each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
