PROBLEM TO BE SOLVED: To efficiently absorb energy on the pressure receiving face of a protecting net while avoiding the breakage of a damper device. SOLUTION: The damper device includes a first axial force absorbing body 10 fixed at its base end and erected in a tiltable manner, a second axial force absorbing body 20 intersecting the first axial force absorbing body 10, and fixed at its base end and erected in a tiltable manner, a first connection material 31 connecting the free end of the first axial force absorbing body 10 to the free end of the second axial force absorbing body 20, a second connection material 32 connecting the free end of the first axil force absorbing body 10 to the base end of the second axial force absorbing body 20, and an anchor 56 anchoring the base end of the first axial force absorbing body 10. One or both of the first and second axial force absorbing bodies are constituted of a plurality of curved flexible materials. COPYRIGHT: (C)2011,JPO&INPIT |
