SLIDING BEARING
To provide a sliding bearing having a function for attenuating energy in addition to a function for supporting an upper structure movably in a horizontal direction.SOLUTION: In a sliding bearing 20 disposed between an upper structure 12 and a lower structure 14, and supporting the upper structure 12 horizontally movably on the lower structure 14, the sliding bearing 20 includes a leg portion 22 projected from the upper structure 12 in a manner that its lower end is applied as a downward sliding face 26A, and a container 32 disposed on the lower structure 14 and housing the leg portion 22. The container 32 has a bottom plate portion 36 having an upward sliding face 36A kept into contact with the downward sliding face 26A and supporting a load of the upper structure 12, and a peripheral wall portion 38 erected from a periphery of the bottom plate portion 36, a magnetic viscous fluid F in which the leg portion 22 is immersed, is housed in the container 32, viscosity of the magnetic viscous fluid F is changed by changing magnetic field applied to the magnetic viscous fluid F, and a coil 50 is disposed as a magnetic field application portion for adjusting resistance of the magnetic viscous fluid F to the leg portion 22 in moving the leg portion 22.SELECTED DRAWING: Figure 2
【課題】上部構造体を水平方向に移動可能に支持する機能に加え、エネルギーを減衰する機能を有している。【解決手段】上部構造体１２と下部構造体１４の間に配置され上部構造体１２を下部構造体１４上で水平方向に移動可能に支持する滑り支承２０であって、滑り支承２０は、上部構造体１２から突設されその下端が下向き滑り面２６Ａとされた脚部２２と、下部構造体１４に設けられ脚部２２が収容される容器３２とを備え、容器３２は、下向き滑り面２６Ａに接触し上部構造体１２の荷重を支持する上向き滑り面３６Ａを有する底板部３６と、底板部３６の周囲から起立された周壁部３８とを有し、容器３２に、脚部２２を浸漬させる磁性粘性流体Ｆが収容され、磁気粘性流体Ｆに印加する磁場を変化させることで磁性粘性流体Ｆの粘性を変化させ、脚部２２の移動時における脚部２２に対する磁気粘性流体Ｆの抵抗を調整する磁場印加部としてのコイル５０が設けられている。【選択図】図２
