To provide a float resistor which can suppress a float of a spherical slide pivot by a simple constitution.SOLUTION: In a float resistor 1 arranged between a lower structure 11 and an upper structure 12 together with a seismic isolation mechanism 20, the float resistor 1 has: a lower-side rail 30 fixed to the lower structure 11; a lower-side slider 33 movably attached to the lower-side rail 30; an upper-side rail 31 fixed to an upper-side construction 12 in an orientation intersecting with the lower-side rail 30; an upper-side slider 34 movably attached to the upper-side rail 31; a connection part 40 for connecting the lower-side slider 33 and the upper-side slider 34 relatively immovably in a horizontal direction, and relatively movably in a vertical direction; and an elastic member 50 arranged between the lower-side slider 33 and the upper-side slider 34, and imparting a downward elastic force to the upper-side slider 34 when the upper-side slider 34 relatively moves upward with respect to the lower-side slider 33.SELECTED DRAWING: Figure 6
【課題】簡単な構成で球面すべり支承の浮き上がりを抑制することが可能な浮き上がり抵抗装置を提供する。【解決手段】下部構造物１１と上部構造物１２との間に免振機構２０とともに設けられる浮き上がり抵抗装置１であって、下部構造物１１に固定された下側レール３０と、下側レール３０に移動自在に装着された下側スライダ３３と、上部構造物１２に、下側レール３０に交差する向きで固定された上側レール３１と、上側レール３１に移動自在に装着された上側スライダ３４と、下側スライダ３３と上側スライダ３４とを、水平方向に相対移動不能且つ上下方向に相対移動自在に連結する連結部４０と、下側スライダ３３と上側スライダ３４との間に設けられ、上側スライダ３４が下側スライダ３３に対して上方へ相対移動したときに上側スライダ３４に下向きの弾性力を付与する弾性部材５０と、を有することを特徴とする浮き上がり抵抗装置１。【選択図】図６
