Furthermore, the container fixing device 1 of this embodiment forms a container fixing state with the movable convex portion 43 rotated to its maximum within the hollow portion 151a. That is, in this container fixing state, the movable convex portion 43 is prevented from rotating by the rotation preventing portion 433, and a gap exists between the first inclined surface 430 of the movable convex portion 43 and the rear corner portion D.
  • the container securing device 1 When the container is in an unlocked, secured state and a pull-out operation is performed, the container securing device 1 rises straight up until the first inclined surface 430 comes into contact with the rear corner D, and then, when the first inclined surface 430 comes into contact with the rear corner D, it maintains this contact state and is lifted diagonally upward (to the upper left in Figure 11).
  • the convex top portion 422 moves while contacting the opening vertical surface portion A.
  • the container fixing device 1 forms the container fixing state when the movable convex portion 43 is rotated to the maximum extent within the hollow portion 151a, but is not limited to this structure.
  • the container fixing device 1 may be structured such that the container fixing state is formed when the movable convex portion 43 comes into contact with the inner corner portion D located at the inner side of the opening 151b during the rotational movement.
  • the flange portion 2 comes into contact with the outer surface portion C of the corner fitting 101a, and the movable convex portion 43 comes into contact with the inner corner portion D located at the inner side of the opening 151b during the rotational movement, so the gap between the movable convex portion 43 and the groove hole 151 can be made small. This makes it possible to stack many containers, and has the advantage of reducing container transportation costs.
  • the container fixing device 1 is not limited to a structure having a movable convex portion 43 with a bifurcated convex structure, and may be a container fixing device 1A as shown in FIG. 12.
  • the lower support portion 4 of the container fixing device 1A is equipped with a lower cone (first fitting portion) 41A consisting of a fixed convex portion.
  • the other parts of the container fixing device 1A are similar to the configuration of the container fixing device 1, for example.
  • the lower cone (first fitting portion) 41A is not limited to a bifurcated convex structure, and may be a general single convex structure.
  • a container fixing device 1B shown in Figs. 13 and 14 can be used.
  • a cylindrical socket portion 61d is fitted into the tip side of the square shaft 61a.
  • This socket portion 61b can be fitted into the flange portion 2 from the side where the operating handle 63 is located.
  • a coil spring 61f is attached to the outer periphery of the square shaft 61a between the base of the rotating engagement member 62 and the end of the rotating shaft 61.
  • a hole into which a spring pin 65 can be driven is formed in a position of the rotating shaft 61 close to the operating handle 63.
  • the container fixing device 1B also includes a stopper 5A.
  • the stopper 5A is made up of a first part 54 and a second part 55.
  • the first part 54 has a gate-like shape with an opening from the center to the bottom side, and the second part 55 has a shape that fits into the opening from below. With the second part 55 fitted into the opening, the first part 54 and the second part 55 are integrated by screwing in a bolt 56.
  • a recess 54a is formed on the back surface of the first part 54, and a recess 55a is formed on the back surface of the second part 55.
  • a ball plunger 28 (ball pressing member) is attached in a hole that extends from the surface of the flange portion 2 to the above-mentioned back surface of the stopper 5A. The movement position of the stopper 5A is maintained by fitting the ball of the ball plunger 28 into one of the multiple recesses 54a, 55a formed in the stopper 51A.
  • the stopper 5A and other components of the container fixing device 1B can also be applied to the container fixing device 1 shown in FIG. 1 and the container fixing device 1A shown in FIG. 12.
