ENERGY ABSORPTION MECHANISM
PROBLEM TO BE SOLVED: To provide a more efficient energy absorption mechanism.SOLUTION: An energy absorption mechanism is fixed by a columnar material extending in a vertical direction and/or a structural material extending in a horizontal direction, and a bracing material extending diagonally. The energy absorption mechanism includes a first spring member and a second spring member, and is formed by assembling the first spring member and the second spring member. The first spring member has a first spring constant K1 between 1.5 and 7.5 kN/mm. The second spring member has a second spring constant K2 between 5.0 and 75.0 kN/mm, and satisfies a following formula 1. Furthermore, a K value derived by the following formula 2 is between 1.4 and 4.9. K1
