Shock absorber and packaging system

Abstract

A shock absorber includes a base structure and a shock-absorbing rib structure. The base structure has a space to accommodate an object to be packaged. The shock-absorbing rib structure is disposed on a face of the base structure. The shock-absorbing rib structure includes a main buffer and an auxiliary buffer. The main buffer is supported by the base structure and has a cubic or rectangular parallelepiped shape. The auxiliary buffer is supported by the base structure at opposed ends of the auxiliary buffer and apart from the base structure between the opposed ends of the auxiliary buffer.
