The other end of the diagonal rod 29 is inserted into the coupling portion external extension 391 and inserted into the diagonal coupling portion 39, and the diagonal rod 29 is held by the coupling portion coupling portion 392, so that the diagonal rod 29 is coupled to the coupling portion coupling portion 392. , So that it can be rotated in the space between the joint outer extension 391 and the joint inner extension 393 (see FIG. 29). The included angle between the diagonal bar 29 and the vertical bar 21 changes from θ1 to θ1 ′.

  As shown in FIGS. 23 to 28, the diagonal bar 29 rotates in the central diagonal groove 54 and the diagonal coupling part 39, and between the diagonal bar 29 and the vertical bar 21 (or horizontal bar 22). Pallet frames 2 having different shapes such as different sizes, squares, and long shapes can be formed at the included angle. This part will be further described below with reference to the drawings. As shown in FIGS. 24 and 27, the total length L1 of the assembly-type pallet 1 (that is, the distance between the two first base seats 3 in the vertical direction opposite to each other) and the total width L2 (that is, two in the horizontal direction) For example, when the overall length L1 and the overall width L2 of the assembly-type pallet 1 are 1100 cm, the diagonal bar 29, the vertical bar 21, and the horizontal bar 22 The included angle θ1 is 45 degrees, the included angle θ2 is 90 degrees, and the included angle θ3 is 45 degrees.
