果が劣るという問題があった。As shown in FIG. 6 (A), the load collapse prevention device of the above-mentioned conventional example assumes that the tightening belt T is loaded on the assumption that the load W is loaded in the load box K. A lock H1 for locking is formed near the outer edge of the luggage box K. Therefore, when loading the cargo W into the luggage box K and locking the tightening belt T, the loaded cargo W is loaded so as to face the stopper H1, so that the outer surface of each of the stacked cargo W is Although the tightening belt T can be routed so as to be substantially along with, as shown in FIG. 6 (B), for example, after the load W is unloaded, or when a relatively narrow load W is loaded, the fastening belt H1 and When the fastening belt T is hooked on the fastener H1 by widening the gap between the loads W, the fastening belt T
When the tightening belt T is slanted around and locked in such a manner that the tightening belt T can hold down only the upper end side of the load W because the slant is drawn around the upper end corner of the load W. The lower load W cannot be suppressed, and particularly when a heavy load W is transported, the lower load W easily collapses due to centrifugal force during traveling on a curve, and the load collapse prevention effect is poor. There was a problem.

の荷崩れを防止できる。First, the rear opening of the packing box 1 (not shown)
Then, for example, a load W in which canned beverages are packed in a box is stacked on a pallet B, and the pallet B is loaded into the front storage chamber 6 by the roller conveyor 31 pivotally supporting the load box 1, and after being fully loaded in the front storage chamber 6. , A partition plate 2 provided inside the packing box 2,
2 is closed and the load W is loaded in the storage chamber 6 on the rear side. Thus, the tightening belt 9,
9A is to be hung, but the tightening belts 9 and 9A and the restraining rods 15A and 15 connected to the tightening belts 9 and 9A
B and 15C are stored in the ceiling portion 1B of the luggage box 1 by the torsion spring 14 of the winding device 10, and the respective restraining rods 15A and 15C thereof.
B and 15C are restrained in the upper stage and the pull-down belt 23 connected to the rod 15A is pulled downward against the urging force of the torsion spring 14. Then, the hook 28 of the lock belt 26 connected to the lower holding rod 15C via the fixing belt 24 is hooked on the stopper 27 provided on the floor surface 1A of the packing box 1, and thereafter, the upper and lower holding rods 15C.
The length of the fixing belt 24 is adjusted with the buckle 25 so that the tightening belts 9 and 9A connected to A and 15C are in a tensioned state.
At this time, the fixing belt 24 is, as shown in FIG.
Since the upper holding rod 15A is folded back from 15C to the upper holding rod 15A, when the fixing belt 24 is pulled downward through the lock belt 26, the upper holding rod 15A, which is stretched around the fixing belt 24, is pushed down, while the fixing belt 24 is connected. The lower holding rod 15C is pulled upward, and the upper and lower holding rods 15A and 15C are relatively moved.
Since the space between the two is narrow, the two-joint link arms 16 and 16 pivotally attached to the upper and lower holding rods 15A and 15C bend in a dogleg shape,
Along with this, as shown in FIGS. 1 and 2, the middle-stage restraining rod 15B pivotally attached to the tips of the link arms 16 and 16 projects to the inside of the luggage box 1. That is, the two-joint link arms 16 and 16 pivotally attached to the restraining rods 15A, 15B, and 15C are interlocked with the locking operation of the lock belt 26, and are bent in a dogleg shape inside the luggage box 1. As shown in Fig. 5, the middle restraint bar 15B is in close contact with the side surface of the stacked load W, and the tightening belt 9 passed through the inside of the middle restraint bar 15B is in close contact with the upper end of the load W toward the side surface.
