PROBLEM TO BE SOLVED: To provide a damper device in which the deformation performance of a viscoelastic body is sufficiently utilized and a stopper is not damaged.;SOLUTION: In this damper device 10, a viscoelastic damper 100 having the viscoelastic body sheared and deformed according to an input vibrational load to absorb a vibrational energy and a frictional damper 200 are connected in series to each other. The viscoelastic damper 100 comprises a stopper 170 obstructing the advancement of the shear deformation of the viscoelastic body when or immediately before the shear strain of the viscoelastic body forming the viscoelastic damper 100 reaches the shear fracture strain.;COPYRIGHT: (C)2008,JPO&INPIT
