<p>In the present invention, a cylindrical body is appropriately deformed up to the latter half of compressive deformation, and predetermined impact-energy-absorbing performance is stably obtained until the end while an adequate compression stroke is ensured. A first bracket (40) for fixing a cylindrical body (20) to a mounting plate (22) has a fixing plate (44) fixed across three side walls (30, 34, 36), the fixing plate (44) comprising corner parts (56, 58), and the first bracket being fixed to the mounting plate (22) via a connecting plate (46). In this case, rigidity is increased by the presence of the corner parts (56, 58), and the cylindrical body (20) can be fixed with high positioning strength; therefore, the orientation of the cylindrical body (20) is appropriately maintained up to the latter half of compressive deformation, and the impact-energy-absorbing performance derived from the crushing of the cylindrical body (20) is obtained in a stable manner until the end. Since incisions (60, 62) are provided in the corner parts (56, 58), the cylindrical body (20) is allowed to deform; therefore, an adequate compression stroke can be ensured while preserving a predetermined level of impact energy-absorbing performance.</p> |
