Description of the Related Art Conventionally, there has been known a synthetic resin pallet in which an opening for a handle is formed in a region other than the central portion of the deck board of the synthetic resin pallet, for example, in the region of the deck board where a fork insertion hole is located. I have.

[0003]

In the above-mentioned conventional pallet made of synthetic resin, an opening for a handle is formed in a region other than the central region of the deck board, so that one worker can work in the opening. When the synthetic resin pallet is lifted by hand, the pallet made of plastic is lifted in a poorly balanced and stable condition, and the pallet is stacked or placed on a conveyor line such as a conveyor. There was a problem that it became difficult.

[0004] The operation of lifting a synthetic resin pallet by one worker will be described in more detail. The worker holds one hand upside down, grasps the upper edge of the opening of the fork insertion hole, and holds the other hand. The hand is inserted into the handle opening formed on the deck board in a straightforward manner, and the side of the synthetic resin pallet is placed on the waist and lifted up. In this way, the synthetic resin pallet is lifted, and the synthetic resin pallet is placed horizontally on a transport line or the like, and the opening for the handle formed on the deck board is formed at the center of the deck board. If it is formed in a region other than the region, the balance is poor when the synthetic resin pallet is lifted, and it is difficult to maintain the synthetic resin pallet in a horizontal state. If the synthetic resin pallet is placed on a transfer line or the like while the synthetic resin pallet is tilted,
There is a problem that a corner or an end of the synthetic resin pallet collides with a transfer line or the like, and the synthetic resin pallet or the transfer line is damaged.

Further, there is also known a pallet described in Japanese Patent Application Laid-Open No. Hei 10-194281, in which an opening for hand holding is provided closer to the center of the pallet than a quarter of its length from the pallet end face. Japanese Patent Laid-Open No. 10-194
The opening for holding the pallet described in Japanese Patent Publication No. 281 is obviously formed in the area of the deck board where the fork insertion hole is located. Thus, in the area of the deck board where the fork insertion hole is located, When an opening for a handle is formed, there is a problem that the strength of this region where the strength is originally reduced is further reduced, and the strength and rigidity of the synthetic resin pallet are greatly reduced.
