PURPOSE:To attenuate resonance amplitude peak by providing a vibration restraining member forming a vibration restraining layer and a restricting member forming a restricting layer on a coupling member for coupling a fly mass body with a bearing device. CONSTITUTION:A coupling member 13 is provided to coupling a fly mass body 11 made of a fly wheel 10 with a bearing device 12. To the coupling member are secured fixedly vibration restricting layer forming members 14, 16 consisting of vibration restricting resin layers resenting vibration restricting action. Also, on these members 14, 16 are further secured fixedly restricting layer forming members 15, 17 made of laminated restricting plates. When an exciting force acts periodically on the fly mass body 11 from the exterior, the deformation of vibration restraining layers 14, 16 caused by the displacement of coupling member 13 is restricted by the restricting layers 15, 17 to generate the shear deformation of vibration restraining layer and absorb vibrational energy. |
