PROBLEM TO BE SOLVED: To provide a sliding base isolation mechanism which shows a superior constructability, profitability and maintainability and in which turning of a sliding element can be controlled.SOLUTION: A sliding base isolation mechanism 20 is provided which is constituted of an upper shoe 21 fixed to the bottom part of an upper structure, a lower shoe 22 fixed to the upper part of a lower structure, and a sliding element 23 provided between the upper shoe 21 and the lower shoe 22. Sliding surfaces 24, 25 abutted on each other of the sliding element 23 and the upper shoe 21 are formed as upwardly slant surfaces inclined in an inverse-V shape along one direction (X-X) and sliding surfaces 26, 27 abutted on each other of the sliding element 23 and the lower shoe 22 are formed as downwardly slant surfaces inclined in a V shape along the other direction (Y-Y). The sliding surface 25 at the upper side of the sliding element 23 and the sliding surface 24 of the upper shoe 21 are provided with upper engaging salient 30 and a guide groove 32 extending in one direction (X-X) and engaged with each other, and the sliding surface 27 at the lower side of the sliding element 23 and the sliding surface 26 of the lower shoe 22 are provided with lower engaging salient 31 and a guide groove 33 extending in the other direction (Y-Y) and engaged with each other.
【課題】施工性、経済性、メンテナンス性に優れ、摺動子の回動を制御することが可能な滑り免震機構を提供する。【解決手段】上部構造体の底部に固定される上沓２１と、下部構造体の上部に固定される下沓２２と、上沓２１と下沓２２の間に介装される摺動子２３からなる滑り免震機構２０において、摺動子２３と上沓２１の互いに当接する摺動面２４、２５を一方向（Ｘ−Ｘ）に沿って逆Ｖ形に傾斜する上部傾斜面として形成し、且つ摺動子２３と下沓２２の互いに当接する摺動面２６、２７を他方向（Ｙ−Ｙ）に沿ってＶ形に傾斜する下部傾斜面として形成する。摺動子２３の上部側の摺動面２５と上沓２１の摺動面２４に、一方向（Ｘ−Ｘ）に延設され、互いに係合する上部の係合凸部３０とガイド溝３２を設け、摺動子２３の下部側の摺動面２７と下沓２２の摺動面２６に、他方向（Ｙ−Ｙ）に延設され、互いに係合する下部の係合凸部３１とガイド溝３３を設ける。【選択図】図２
