According to the present invention as set forth in claim 1, the inside of the cylindrical girders at the corners is partitioned by the corner partition walls extending over the front and back surfaces, and the inside of the intermediate tubular girder is partitioned by the intermediate partition walls extending over the front and back surfaces. Since it is partitioned, the corner tubular girder is partitioned by the corner partitioning wall, and the intermediate tubular girder is partitioned by the intermediate partitioning wall to reinforce the corner tubular girder and the intermediate tubular girder, Moreover, a plurality of upper rails are installed between the tubular girders at the corners and the tubular girders at the middle above the fork insertion holes between the tubular girders at the corners and the intermediate girders. Matching the connecting parts to the tubular girders at both ends of one of the bars to the connecting parts with the cylindrical girders at the corners of the corner partition wall and the connecting parts with the tubular girder in the middle of the intermediate partition wall, Both ends of the plurality of upper rails installed between the corner tubular girder and the middle tubular girder are connected to the corner tubular girder of the corner partition wall and the intermediate section. The upper bar that matches the connecting portion with the middle cylindrical girder of the wall is a reinforcing upper bar that is thicker than the other upper bar that connects the tubular girder at the corner and the intermediate cylindrical girder. Therefore, the reinforcing upper rail having a large thickness can continuously reinforce the corner partition wall and the intermediate partition wall to reinforce the strength of the surface portion of the fork insertion hole which the fork hits. The upper crosspiece, which is continuously integrated with the connecting portion between the cylindrical girder and the intermediate cylindrical girder of the intermediate partition wall, is connected between the cylindrical girder at the corner and the cylindrical girder at the middle. Since it is a reinforcing upper bar that is thicker than other upper bars, it is possible to effectively reinforce the surface in the direction orthogonal to the fork insertion direction while minimizing the thickened part, which allows the use of resin. With the amount kept as low as possible and the rational structure to improve the strength, It is lifted by inserting the forks Fork insertion hole in which the pallet can provide a synthetic resin pallet of hard modified configuration.

A plurality of lower bars are installed between the tubular girders at the corners and the middle tubular girder, and the connecting portions to the tubular girders at both ends of one of the lower bars are connected to the corner partition wall. Since the connection portion with the cylindrical girder at the corner and the connection portion with the intermediate cylindrical girder of the intermediate partition wall are made to coincide with each other, the back surface of the pallet can be effectively reinforced.

According to the invention of claim 3, in addition to the effect of the invention of claim 1, the intermediate partition wall is parallel to the side of the pallet where the intermediate partition wall is present in plan view. However, since the intermediate partition wall and the reinforcing upper rails on both sides that are continuous with the intermediate partition wall are in a straight line in plan view, the intermediate partition wall and the reinforcing upper rails on both sides that are continuous with this are in a straight line in plan view. With a rational structure, the surface can be reinforced in the direction orthogonal to the fork insertion direction.

According to the invention of claim 4, in addition to the effect of the invention of claim 1 or claim 3, the corner partition walls are L-shaped in plan view and each L-shaped. The sides are parallel to the two sides that are adjacent to each other at right angles in the corners of the pallet, and the L-shaped corner partition walls are provided on the tubular girders located at the four corners of the pallet in plan view. Since the intermediate partition wall provided on the two intermediate tubular girders and the reinforcing upper rail connecting the tubular girders at the adjacent corners and the intermediate tubular girder constitute a square annular annular reinforcing portion, The L-shaped corner partition wall, middle partition wall, thickened reinforcing upper bar, and lower bar are continuous in the shape of a square ring so that the surface of the pallet and thus the entire pallet can be reinforced. Even if you insert the fork into the fork insertion hole and lift it up, the annular reinforcement will keep the same condition. Those capable of providing a hard pallet deformed can form prevented.
