摘要

An inexpensive damper mechanism for a base isolation structure having a low height is provided. A vibration isolation structure damper mechanism (30) is provided between a lower structure (20) and an upper structure (10) provided above the lower structure (20), the lower structure (20) and the upper structure The displacement reduction mechanism 31 has a link mechanism, and has a displacement suppressing portion 32 that absorbs energy by deformation and reduces the displacement.
