PROBLEM TO BE SOLVED: To provide a pallet which is structured to be capable of exhibiting higher strength against a vertical load while reducing a weight. SOLUTION: The pallet 11 is integrally molded of a synthetic resin and comprises adjacent beams 21 and 22 which are coupled with each other by an upper bar 31 and a lower bar 32. Upper and lower in-beam bars 51 and 53 are provided at positions where they do not vertically overlap at upper and lower ends of the beams 21 and 22. The respective in-beam bars 51 and 53 are equipped with vertical portions 51b and 53b extending in the same plane as that of the upper bar 31 through a joint 61. An upper vertical rib 62 extending along an inner side face of the beams 21 and 22 short of the vertical portion 53b of the lower in-beam bar is hanging at a lower end of an end of the vertical portion 51b of the upper in-beam bar. A lower vertical rib 63 extending along an inner side face of the beams 21 and 22 short of the vertical portion 51b of the upper in-beam bar is made to stand at an upper end of an end of the vertical portion 53b of the lower in-beam bar. Leading edges of both ribs 62 and 63 are joined with each other by 10 mm or more. COPYRIGHT: (C)2003,JPO
