A connection unit for connecting and fixing two foldable pallets stacked up and down with each other is installed with the same structure composed of a fastening slot for connecting and fixing a frame to the support frame and a hole formed between the fastening slots, the fixing A protrusion formed protruding on the upper surface of the connection bracket provided on the folding pallet disposed below the foldable pallet is inserted into the hole of the frame, and the two foldable pallets stacked up and down are connected and fixed.

However, in the conventional foldable pallet such as the prior art, welding is partially performed in many places on the pallet in order to solve the inconvenience of quick productivity and use. give.

In addition, in the prior art, since vertical and horizontal frames are not foldable in half, when taking out various items contained in a pallet, before separating the vertical and horizontal frames from the base frame, Since the withdrawal operation is impossible, there is a lot of trouble in use.
