Claims

[Scope of utility model registration request]

For a floor structure having corner fittings 5, 5 above and below column bases 4 at the four corners of the floor, an end wall 6 having a corner post 8 having a corner fitting 7 on the upper part is pivotably supported to be able to rise and fall. The Hemi container has a spring device 13.13 pivotally connected at one end to the floor structure side and at the other end to the end wall 6 side, the spring device 13.1
3 has a pin hole 14 at one end and a large diameter head 17 at the other end.
8, a bottom plate 20 having a hole 20a at one end through which the rod 17 is inserted, and a pin hole 21 at the other end.
It consists of a cylindrical body 18 having a support piece 21 having a diameter of 1.a, and two compression coil springs 19 and 19a having different acting directions. The compression coil spring 19a is located between the large-diameter head 17a of the cylinder and the bottom plate 20 of the cylinder, and the compression coil spring 19a is fitted into the bottom plate 20 of the cylinder and the rod 17, and is connected to the disk 22 whose position in the axial direction can be moved with a nut 23. An end wall rotating device for a folding container, characterized in that the end wall rotating device is located between the ends of the folding container and is configured to balance the weight of the end wall 6 over the entire range in which the end wall 6 is raised and fallen.
