ABSTRACT:
A compressive/tensile-load-type lead damper absorbs vibration energy by elastic-plastic deformation through bending of lead. The lead damper has a semicircular structural portion at a central portion, and compressive/tensile load input points at opposite ends of the semicircular structural portion. The center of an imaginary circle that overlaps the semicircular structural portion is located on a line connecting the load input points. The lead damper deforms by only a small amount upon receipt of compressive/tensile load and has a compact structure.
