Impact absorbing member

Abstract

An impact absorbing member includes: a first wall and a second wall that face each other; a plurality of side walls connecting these first wall and second wall; a corner portion connecting the side walls; and a destruction inducing portion, located within a predetermined area from the corner portion, for destroying the corner portion when the first wall or the second wall receives impact.

What is claimed is: 
     
         1 . An impact absorbing member comprising:
 a first wall and a second wall, the walls facing each other;   a plurality of side walls connecting these first wall and second wall;   a corner portion connecting the side walls; and   a destruction inducing portion, located within a predetermined area from the corner portion, for destroying the corner portion when the first wall or the second wall receives impact.   
     
     
         2 . The impact absorbing member according to  claim 1 , wherein the destruction inducing portion includes a thin portion, and has a substantially polygonal prism shape whose side surface is open. 
     
     
         3 . The impact absorbing member according to  claim 2 , wherein the destruction inducing portion has a substantially quadrangular prism shape. 
     
     
         4 . The impact absorbing member according to  claim 1 , wherein the destruction inducing portion is formed at the side wall within a predetermined area from the corner portion. 
     
     
         5 . The impact absorbing member according to  claim 1 , wherein at least one of the first wall side or the second wall side includes a depression having higher stiffness than the destruction inducing portion. 
     
     
         6 . The impact absorbing member according to  claim 5 , wherein the depression has a surface substantially parallel with a direction to receive impact.
