[0095] respectively expressed as: figure 1 is a front view of the connector for the container according to the first embodiment of the present invention, figure 2 is a top view, image 3 is the right side view, Figure 4 is the left view, Figure 5 is a plan view. And, respectively expressed as: Figure 6 to Figure 8 is an explanatory diagram of the rotation position of the upper and lower cones, Figure 9 to Figure 12 It is an explanatory diagram of the operating state of the connector. According to its function and structure, this connecting piece is called container fastening twist lock (twist lock). In addition, the description in the "Example" column below also describes the case of loading and unloading a plurality of containers. Therefore, in the case of securing the container to the deck, in the following descriptions, replace "upper container" with "container", and "the lower corner casting of the upper container" with "the lower corner casting of the containe...
