PURPOSE:To obtain an element absorbing a large amount of energy further generating less crack due to a shock, by mutually connecting plural wave-like ribs with ribs. CONSTITUTION:Connecting ribs B1, B2 are provided between laterally extended transverse ribs A1 and A2, connecting ribs B3, B4 between transverse ribs A2 and A3 and connecting ribs B5, B6 between transverse ribs A3 and A4. It is preferable to connect the connecting ribs crossing almost at a right angle with the transverse ribs. In this way, an excellent energy absorbing element, absorbing a large amount of energy and causing no abnormality of cracks or the like due to a shock, can be obtained. |
