    • PROBLEM TO BE SOLVED: To solve the problem that impact to an occupant is large because reaction force rapidly decreases and impact energy cannot be absorbed more than it when once a plurality of recessed groove structures reaching the other end from an end part of an impact receiving surface side buckle and collapse though they are instantly deformed while work-hardening until they buckle and collapse by an impact load. SOLUTION: The problem is solved by a two stage type impact cushioning and absorbing effect to cushion initial impact of collision by deformation of a zigzag rib slightly low in rigidity at first and to absorb most part of the impact energy by deformation of respective parallel ribs of a high impact receiving surface side recessed part high in rigidity and a vehicle body mounting surface side recessed part as a plurality of the impact receiving surface side recessed parts 4 and a plurality of the vehicle body mounting surface side recessed parts 5 are arranged with the zigzag rib 6 between them while alternately translating them zigzag and the parallel ribs 7, 8 are respectively arranged between the impact receiving surface side recessed parts and between the vehicle body mounting surface side recessed parts.
