<p>The purpose of the present invention is to provide an energy absorption member having sufficiently low axial resistance at an early stage of collision but capable of absorbing a sufficiently large amount of energy throughout collision. The energy absorption member (11) has an approximately cylindrical shape with openings (12, 12) at both ends. A plurality of convex parts (13) adjoining or close to each other are formed on the side surface of the cylindrical shape. The convex parts (13) protrude toward the inside of the cylindrical shape. Since the convex parts (13) protrude toward the inside of the energy absorption member (11), axial resistance can be reduced at an early stage of collision, and the total amount of impact energy absorption can be increased.</p> |
