Abstract
A lightweight shock absorber has an ideal F-S waveform, and is formed of a foam resin material. The cross-sectional area of the absorber in the compression axis direction and the vertical direction changes at least partially in the compression axis direction, and consequently the relation between distortion and compressive stress in the compression axis direction (F-S waveform) is approximately linear.
