PURPOSE:To hold strong rib structure while simplifying insertion and removal of a fork of a hand lifter by providing a tilting rib or a slope at an edge of an insertion side and an edge of an opening which face a fork insertion hole formed in a shape of parallel-crosses between cylindrical beams. CONSTITUTION:A surface 1 and a rear face 2 of a palette made of synthetic resin is so constituted that fork insertion holes 6 are formed in a shape of parallel-crosses between cylindrical beams 3, 4, 5 which connect with each other at the corners, the middle points and the center points. Bars 13, 13' are formed between the cylindrical beams 4 and 5, and a plurality of tilting ribs 15 are provided. This allows a fork of a hand lifter to pass by the bars 13, 13' smoothly. T-shaped bars 16, 17 are provided at a point where the cylindrical beams 3 and 4 are connected, and a tilting rib 18 is provided at an edge of a fork insertion side and an edge of an opening 19 of the fork to allow the fork to pass through easily. |
