To provide an impact absorbing structure for a vehicle enhancing durability during the time when a load is applied and a complete compressive deformation occurs in an axial direction, while achieving high performance weight efficiency in terms of impact absorbing performance.
The structure comprises an inner cylindrical body 2 and an outer tubular body 3. In the inner cylindrical body 2, vertical cross sections at positions separated oppositely in the axial direction by a predetermined distance from a predetermined position form a regular hexagon formed by rotating the regular hexagon located at the predetermined position approximately 30° (180°/6) around the axis; and lines connecting each side 21 to each apex 22 of each regular hexagon are used as a valley fold portion 23 or a crest fold portion 24 to form a substantially triangle plane portion 25A between the valley fold portion 23 and crest fold portion 24 regularly and continuously. The outer tubular body 3 has a cross-sectional shape circumscribed to each apex 22 of each regular hexagon of the inner cylindrical body 2 with inner spherical parts abutting on each apex 22 and connected, and cover the inner cylindrical body 2.
