In FIG. 4, as shown in FIG. 4, a force F acting in the axial direction of the first wires 9a and 9b is applied to the inner and outer sides of the second wire 10 by one first wire 9a and the other first wire 9b. As a result, the strength of each of the lattice members 3 to 6 with respect to the force acting in the axial direction of the first wires 9a and 9b is increased.
Therefore, since the strength is not increased by increasing the number of the first wires as in the conventional case, the first wire is maintained while maintaining the necessary strength.
The number of wires 9a and 9b can be reduced, whereby the weight and cost of each of the lattice members 3 to 6 can be reduced.

One load F acts in the vertical direction. On the other hand, since the axes of the first wires 9a and 9b of the left and right side lattice members 5 and 6 are in the vertical direction, the vertical buckling strength of the left and right side lattice members 5 and 6 is increased. Therefore, the left and right side lattice members 5, 6 of the lower article storage device 1 can sufficiently support the load of the upper article storage device 1 in strength.

Further, when the article storage devices 1 are stacked one above the other as described above, the load concentrates below the legs 8 of the upper article storage device 1, while the load acts on the lower part of FIG.

6 sufficiently withstands the load of the upper article storage device 1 in strength,
Further, the labor and cost for installing a partial reinforcing member can be saved.

When the article storage devices 1 are vertically stacked as described above, the front lattice member 3 and the rear lattice member 4
In this case, since the load of the left and right side grid members 5 and 6 is not applied, the diameters of the first wire members 9a and 9b are increased by the increased strength of the front grid member 3 and the rear grid member 4. Even if the diameter is smaller than the diameter of the second wire rod 10, sufficient strength is maintained, and further weight reduction can be achieved.

When the article storage tools 1 are vertically stacked as described above, as shown in FIG. 19, the vertical surfaces 47 of the left and right legs 8 of the upper article storage tool 1 are connected to the lower article storage tool. By engaging with the outer sides of the upper ends of the left and right side lattice members 5, 6, the upper article storage device 1 can be prevented from dropping to the left and right sides of the lower article storage device 1.
