The above-mentioned synthetic resin pallet P is
The pallet P made of synthetic resin may be separately formed on the upper deck board 10 side and the lower deck board 11 side by injection molding or the like, and then the upper deck board 10 side and the lower deck may be formed. The board 11 side can also be formed by welding the corner girder 12, the middle girder 13 and the center girder. In the above-described embodiment, the four sides of the synthetic resin pallet P
A so-called four-sided synthetic resin pallet P in which two fork insertion ports 14 are formed is shown, but two forks are provided only on one of the two opposing side surfaces. The present invention can also be applied to a so-called two-way synthetic resin pallet in which the insertion port 14 is formed.

[0020]

Since the present invention has the above-described structure, the following effects can be obtained.

Since the non-slip tape is attached to the lower horizontal portion formed between the two inclined portions constituting the bottom of the fork insertion opening and having little deformation, the time required for attaching the non-slip tape t is shortened. The anti-slip effect of the anti-slip tape can be sufficiently exhibited.

Since the members constituting the bottom of the fork insertion port are formed with substantially the same thickness, it is possible to prevent the bottom of the fork insertion port from being deformed in the cooling process after injection molding. Accordingly, the bottom of the fork insertion port does not deform into a mountain shape, and the workability of inserting the hand lift into the fork insertion port and taking out the hand lift from the fork insertion port is improved.

Since the reinforcing ribs are formed on the side surfaces of the central vertical rib, the central vertical rib on which the wheel of the hand lift is placed can be reinforced.
