By doing so, the pallet 10 can be lifted and transported. Further, at this time, the fork 42 with a narrow claw width is placed in the upper narrow part 18, and the gap in the width direction suppressed.

For example, as shown in FIG. 9, when inserting a fork 43 of a hand lift with a narrow claw width into the fork insertion hole 16, the fork 43 is inserted into the upper narrow portion 18. At this time, the wheel 44 provided below the fork 43 is placed through the lower narrow portion 19 at a position corresponding to the hand lift wheel opening 20.

As shown in FIG. 10, the wheels 44 are made to protrude below the pallet 10 through the hand lift wheel opening 20, so that the pallet 10 can be lifted and transported by the fork 43. Also, at this time, the fork 43 with a narrow claw width is placed in the upper narrow part 18, and the gap in the width direction suppressed.

Next, the effects of the above embodiment will be described below.
(1) Since the fork insertion hole 16 is provided with a wide wide part 17 and a narrow upper narrow part 18 formed on the upper part of the wide part 17, the forks 41 to 41 with different pawl widths are provided. Stable transportation by each forklift truck with 43 is possible. Specifically, for example, when inserting a fork 41 with a wide claw into the fork insertion hole 16, the pallet 10 can be lifted and transported by inserting the fork 41 into the wide part 17. Furthermore, when inserting the forks 42, 43 with narrow claws into the fork insertion hole 16, by inserting the forks 42, 43 into the upper narrow part 18, the pallet 10 can be lifted and transported, and the pallet 10 can be lifted and transported. This prevents the pallet 10 from shifting in the width direction X with respect to the forks 42 and 43.

(2) Since the additional rib 33 is provided to connect the deck board 12 with the upper narrow side wall 18a that constitutes the side wall of the upper narrow part 18, the upper narrow part 18 of the fork insertion hole 16 has a narrow claw. Deflection of the deck board 12 when the pallet 10 is lifted by inserting the forks 42, 43 can be suppressed. As a result, collapse of the cargo on the deck board 12 can be suppressed.

(3) A plurality of reinforcing ribs 32a are provided to connect the upper narrow side wall 18a, the side walls of the upper girder parts 13b to 15b, which are side walls parallel to the upper narrow side wall 18a, and the deck board 12, and the additional reinforcement ribs 32a are provided. Since the ribs 33 connect the upper narrow side wall 18a and the deck board 12 between the adjacent reinforcing ribs 32a, deflection of the deck board 12 can be further suppressed.

(4) Since the hand lift wheel opening 20 is provided below the upper narrow part 18 of the grounding board 11, the wheel 44 can be moved by hand while inserting the narrow fork 43 of the hand lift into the upper narrow part 18. By projecting downward through the lift wheel opening 20, the pallet 10 can be lifted and transported. Furthermore, by providing the hand lift wheel opening 20 only in the lower part corresponding to the upper narrow part 18, the opening area of the hand lift wheel opening 20 can be reduced compared to the case where it is provided in a wide range below the wide part 17. Can be made smaller. As a result, for example, a decrease in the strength of the grounding board 11 can be suppressed. Further, for example, when a plurality of pallets 10 loaded with articles are stacked, it is possible to reduce the possibility of the articles below biting into the hand lift wheel openings 20 of the pallets 10 stacked above.

(5) Since the fork insertion hole 16 is provided with a narrow lower narrow part 19 formed at the lower part of the wide part 17 and below which the hand lift wheel opening 20 is arranged, the fork 43 of the hand lift When the wheel 44 is inserted into the fork insertion hole 16, the wheel 44 is guided by the lower narrow part 19, so that the fork 43 can be inserted in an accurate position corresponding to the upper narrow part 18. That is, if the lower narrow part 19 is not provided, there is a risk that the fork 43 of the hand lift will be inserted into a position that does not correspond to the upper narrow part 18 and the hand lift wheel opening 20, but this can be avoided. can do.
