According to the present invention, an upwardly opening recess 4 having a concave cylindrical surface 6 extending in a direction perpendicular to the longitudinal direction of the structure is provided in the upper part of the metal lower support member 2 fixed to the upper part of the support structure 1. , a lower convex cylindrical surface 10 extending in a direction perpendicular to the longitudinal direction of the structure formed at the lower part of the metal bearing member 9;
is fitted into the concave cylindrical surface B of the lower support member 2, so the rotation of the structural object 5 is caused by the rotation of the lower convex cylindrical surface 10 of the bearing member 9 relative to the concave cylindrical surface B of the lower support member 2. 4) A downward opening recess 8 having a concave cylindrical surface 7 extending in the longitudinal direction of the relic is provided at the lower part of the metal upper support member B fixed to the relic part of the relic. , since the upper convex cylindrical surface 11 extending in the longitudinal direction of the structure formed on the upper part of the bearing member 9 is fitted into the downward opening 8 of the upper support member B, the upper convex cylindrical surface of the bearing member 9 The concave cylindrical surface 7 of the upper support member B can rotate with respect to the surface 11, so that the upper support member 6 can rotate against the lower support member 2 due to twisting of the artifact 5 or the like.
However, even if the upper support member 6 and the bearing member 9 are inclined in the width direction of the structure, surface contact can be made between the upper support member 6 and the bearing member 9, and the lower support member 2 is made of a metal material.
Since the bearing member 9 and the upper bearing member 6 are always in surface contact with each other, the movable bearing device can be manufactured in a small size and at low cost. Since the expansion/contraction allowable gap 12 is provided between the longitudinal end of the structure, the structure 5 can be freely moved while maintaining surface contact between the lower support member 2, the bearing member 9, and the upper support member 6. Can be expanded and contracted
Further, since a large load from the structure 5 is applied to the fitting portion between the concave cylindrical surface 6 and the lower convex cylindrical surface 10 and the fitting portion between the concave cylindrical surface 7 and the upper convex cylindrical surface 11, the lower support member 2 and the upper bearing member 6 relative to the bearing member 9 i4'
4. Misalignment in the direction of the structure can be prevented, and furthermore, by fitting the lower part of the bearing member 9 with the upward opening recess 4 of the lower support member 2, the longitudinal direction of the structure of the bearing member 9 relative to the lower support member 2 can be prevented. It is also possible to prevent a lateral displacement movement of the lower bearing member 2, the bearing member 9 and the upper bearing member 6 by extremely simple means, and a special J
? Effects such as no need to provide a device can be obtained.
