  "textContent": "A bumper structure which as a whole has a reduced weight and which has sufficient buckling strength. A bumper structure has a box-like outer shape constituted of a front flange (2), a rear flange (3), an upper web (4), and a lower web (5) which consist of a steel material. An intermediate web (6) consisting of a material other than the steel material is disposed between the upper web (4) and the lower web (5). If the Young's modulus of the steel material is E 1 , the density of the steel material is Á 1 , the Young's modulus of the material which forms the intermediate web (6) is E 2 , and the density of the material which forms the intermediate web (6) is Á 2 , the bumper structure satisfies E 1 /Á 1 3 < E 2 /Á 2 3 .",
