## 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 2)

The impact absorbing member according to claim 2, wherein the destruction inducing portion has a substantially quadrangular prism shape.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 5)

The impact absorbing member according to claim 5, wherein the depression has a surface substantially parallel with a direction to receive impact.
