Technical Examples
A skeleton member structure having a tubular structural member (11, 211) filled with granular materials for absorbing impact energy. The granular materials includes a granular material having a hollow portion (12a, 212a) or a porous granular material. When the skeleton member receives an impact, the granular materials are deformed or collapsed, and impact energy is stably absorbed. Since the granular materials are hollow or porous, the weight of the skeleton member filled with the granular materials is reduced.
