PROBLEM TO BE SOLVED: To provide a seism base isolation mechanism which can reduce a friction coefficient between an inclined face and a movable element.SOLUTION: An upper guiding member 2 includes an upper inclined face 21 which inclines so that a center part in a X-direction (one horizontal direction) is upwardly convex along the X-direction; and a lower guiding member 3 includes a lower guiding face 31 which inclines so that a center part in a Y-direction (other horizontal direction) is downwardly convex along the Y-direction orthogonal to the X-direction. A movable element 4 includes: a body part 41; an upper rotor 42 which is rotatably fixed about an axial line extending in the Y-direction at an upper part of the body part 41, the upper rotor being rotatable along the upper inclined face 21; and a lower rotor 43 which is rotatably fixed about an axial line extending in the X-direction at a lower part of the body part 41, the lower rotor being rotatable along the lower inclined face 31. The movable element 4 is initially positioned at a position where the center part of the upper inclined face 21 in the X-direction and the center part of the lower inclined face 31 in the Y-direction overlap.SELECTED DRAWING: Figure 3
【課題】傾斜面と可動子との摩擦係数を小さくすることができる免震機構を提供する。【解決手段】上部案内部材２は、Ｘ方向（一の水平方向）に沿ってＸ方向の中央部が上側に凸となるように傾斜する上部傾斜面２１を有し、下部案内部材３は、Ｘ方向に直交するＹ方向（他の水平方向）に沿ってＹ方向の中央部が下側に凸となるように傾斜する下部傾斜面３１を有し、可動子４は、本体部４１と、本体部４１の上部にＹ方向に延びる軸線回りに回転可能に固定されて上部傾斜面２１に沿って転動可能な上部転動子４２と、本体部４１の下部にＸ方向に延びる軸線回りに回転可能に固定されて下部傾斜面３１に沿って転動可能な下部転動子４３と、を有し、可動子４は、初期状態において上部傾斜面２１のＸ方向の中央部、および下部傾斜面３１のＹ方向の中央部と上下方向に重なる位置に配置されている。【選択図】図３
