PURPOSE:To make it possible to obtain a vibration absorber which has a small size while it has a long oscillating period, by disposing springs between frames and bases, and by providing arms each having a weight, and by providing dampers between the arms. CONSTITUTION:Springs 4, 4A are disposed between frames 3, 3a supported on base 1, 1a by means of rollers 2, 2a through 2i, and the bases 1, 1a. Further, arms 8a, 8a are supported to bearings 7, 7a through 7c secured on the frames 3, 3a, through the intermediary of pins 6, 6a. Further, the arms 8, 8a are provided with weights 9, 9a, and viscoelastic dampers 12, 12a through 12c are disposed between the arms 8, 8a. |
