As shown in FIG. 2, one end and the other end of the linear member 5 are provided with screw grooves for mounting a fixing member. Specifically, the end of the linear member 5 is inserted into a steel bar 10 formed in a predetermined shape, and the steel bar 10 and the linear member 5 are firmly connected to each other by pressing or bonding, and the steel bar 10 is subjected to thread cutting. Thereby, the screw groove is formed. In addition,
The method of providing the thread groove at the end of the linear member 5 is not limited to the above-described method.

線状部材５にかかる負担が軽減される。Further, since the linear member 5 has flexibility, even if a pull-out load acts in a direction different from the vertical direction, for example, in the directions of the arrows b and c, the linear member 5 is accordingly actuated. By being deformed and pulled, the load can be easily absorbed. Since the lower end of the linear member 5 is fixed via the spring 8, when a pulling load in various directions is applied, the displacement between the fixing member and the lower shoe 1 is absorbed to some extent by the spring 8. And
The load on the linear member 5 is reduced.

できる。Further, in this bearing device, when a load around the vertical axis is applied, the upper shoe 3 rotates on the lower shoe 1 via the bearing plate 2 to absorb the displacement around the vertical axis. At this time, since the linear member 5 is installed so as to penetrate through the respective centers of the lower shoe 1, the bearing plate 2, and the upper shoe 3, the linear member 5 may be twisted, or the fixing member and the lower shoe 1 may be twisted. (Or the upper shoe 3) is shifted from each other, thereby absorbing the rotation shift. That is, there is little possibility that the displacement in the rotation direction is hindered. Further, in the present embodiment, a single linear member 5 penetrating through the central portion absorbs pull-out loads in various directions, so that it is possible to easily reduce the size of the apparatus.
