ABSTRACT:
A plastic pallet comprises a pair of deck boards opposed to each other in parallel with each other, a pair of outer girder portions respectively disposed at a pair of opposite side portions of the deck boards, an inner girder portion placed midway between the outer girder portions, and a plurality of reinforcement ribs disposed on respective inner surfaces of said deck boards. Each of the outer girder portions includes a side wall and a first partition wall disposed between the deck boards. The inner girder portion includes a pair of second partition walls which are disposed in parallel with each other with a predetermined distance. The reinforcement ribs existing within a range of a distance extending inward and outward from the first partition wall have a total weight greater than the total weight of the reinforcement ribs existing within a range of the distance extending outward and inward from the second partition wall. With this arrangement, a region around the partition wall of the outer girder portion to be particularly reinforced can be effectively reinforced without wastefully increasing the weight of the pallet.
