SLIDING BEARING
To provide a sliding bearing provided with a function for attenuating energy, in addition to a function for supporting an upper structure movably in a horizontal direction.SOLUTION: A sliding bearing 16A has a downward sliding face 20 disposed on an upper structure 12, and an upward sliding face 22 disposed on a lower structure 14. The downward sliding face 20 is positioned at a central portion 22A of the upward sliding face 22, and the downward sliding face 20 is slid from the central portion 22A of the upward sliding face 22 toward an outer peripheral portion 22B at its periphery, when horizontal force is applied to the upper structure 12 or the lower structure 14. A frictional coefficient of the outer peripheral portion 22B of the upward sliding face 22 is more than a frictional coefficent of the central portion 22A.SELECTED DRAWING: Figure 1
【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持たせた滑り支承を提供すること。【解決手段】滑り支承１６Ａは、上部構造体１２に設けられた下向きの滑り面２０と、下部構造体１４に設けられた上向きの滑り面２２とを有している。下向きの滑り面２０は、上向きの滑り面２２の中央部２２Ａに位置し、上部構造体１２または下部構造体１４に水平方向の力が作用したときに、下向きの滑り面２０は、上向きの滑り面２２の中央部２２Ａからその周囲の外周部２２Ｂに向かって滑動する。上向きの滑り面２２の外周部２２Ｂの摩擦係数は、中央部２２Ａの摩擦係数よりも大きく形成されている。【選択図】図１
