FIGS. 1 to 4 show an embodiment of the present invention. In FIG. 1, reference numeral 10 denotes an aluminum van type packing box mounted on the rear part of a truck 11. Mounting shaft that supports two double-sided partition plates 12
13 are attached to the upper, middle and lower tiers of the side wall of the packing box 10. A mounting hinge 13A for supporting the mounting shaft 13 up and down and a receiving hinge portion to be described later are fixed to the side wall of the packing box 10, and the floor 10A of the packing box 10 is located at the closed position of the partitioning plate 12. A groove 14 into which the lower end of the partition plate 12 is fitted correspondingly.
Are formed. A hinge portion 15 inserted into the mounting shaft 13 is integrally fixed to an outer edge portion of each of the partition plates 12 corresponding to a mounting position on the mounting shaft 13. A receiving hinge portion 16 for supporting the hinge portion 15 is inserted through the
It is attached and fixed to 10 side walls. As shown in FIG. 4, the hinge portion 15 and the receiving hinge portion 16 are each formed in a cylindrical shape, and the lower end surface of the hinge portion 15 and the receiving hinge portion which are the overlapping surfaces of the hinge portion 15 and the receiving hinge portion 16 are formed. On the upper end surface of the hinge 16, the outer periphery of the hinge 15 and the receiving hinge 16 is cut out in a semicircular shape to form cutout recesses 17 and 18.
Projections 19 and 20 are formed on the overlapping surface of the hinge portion 15 and the receiving hinge portion 16 by 17 and 18, respectively. This hinge part 15
The positional relationship between the notches 17, 18 formed in the receiving hinge 16 and the protruding portions 19, 20 is such that the protruding portion 19 of the hinge 15 is received when the partitioning plate 12 is closed. Is formed so as to mesh with the notch concave portion 18 of FIG. That is, when the partitioning plate 12 is completely opened, the projection 19 of the hinge 15 and the projection 20 of the receiving hinge 16 are arranged in a direction orthogonal to each other, and The projecting portion 19 of the hinge portion 15 climbs up, and the hinge portion 15 of the partition plate 12 is supported by the receiving hinge portion 16 attached to the side wall of the packing box 10.
