BASE ISOLATION MECHANISM
To provide a base isolation mechanism capable of preventing a movable element from coming off from an upper guiding member and a lower guiding member when excessive external force is applied, and capable of reducing acceleration transmitted to an upper structure.SOLUTION: A pair of upper cushioning materials has a movable element abutting portion (upper movable element abutting portion) disposed between an upper stopper and a movable element, and a disc spring (upper disc spring) disposed between the movable element abutting portion and the upper stopper. The movable element abutting portion is configured to relatively displace in an X-direction (one horizontal direction) with the upper stopper, and the disc spring is configured to elastically deform in the X-direction. A pair of lower cushioning materials 8B and 8B has a movable element abutting portion 92 (lower movable element abutting portion) disposed between the upper stopper 7 and the movable element 4, and a disc spring 93 (lower disc spring) disposed between the movable element abutting portion 92 and the lower stopper 7. The movable element abutting portion 92 is configured so as to relatively displace in a Y-direction (another horizontal direction) with the lower stopper 7, and the disc spring 92 is configured to elastically deform in the Y-direction.SELECTED DRAWING: Figure 9
【課題】過大外力が作用した際に、可動子が上部案内部材および下部案内部材から外れることを防止できるとともに、上部構造体に伝達される加速度を低減させることができる免震機構を提供する。【解決手段】一対の上部緩衝材は、上部ストッパと可動子との間に配置された可動子当接部（上部可動子当接部）と、可動子当接部と上部ストッパとの間に配置された皿ばね（上側皿ばね）とを有し、可動子当接部は上部ストッパとＸ方向（一の水平方向）に相対変位可能に構成され、皿ばねはＸ方向に弾性変形可能に構成され、一対の下部緩衝材８Ｂ，８Ｂは、下部ストッパ７と可動子４との間に配置された可動子当接部９２（下部可動子当接部）と、可動子当接部９２と下部ストッパ７との間に配置された皿ばね９３（下側皿ばね）とを有し、可動子当接部９２は下部ストッパ７とＹ方向（他の水平方向）に相対変位可能に構成され、皿ばね９２はＹ方向に弾性変形可能に構成される。【選択図】図９
