Abstract
Abstract A pallet made of synthetic resin and including four corner posts, intermediate posts therebetween, a center post, with hollow edge boards connecting the corner posts and the intermediate posts, and hollow deck boards connecting the intermediate posts and the center post. The pallet is formed from four identical complementary elements combined along two crossed division lines, each element provided with the above described hollow edge boards and hollow deck boards, each of which have flat walls provided at both ends thereof to form a closed hollow space therein. Reinforcing ribs are provided in the hollow space in each of the edge boards such that the reinforcing ribs extend parallel to the side surfaces of the pallet and are disposed such that the ribs meet with one another at right angles in the four corners of the pallet. The pallet is assembled by butt fusing the reinforcing ribs and upper and lower flat walls of the elements together.
