PURPOSE:To remarkably enlarge the frequency range of vibration capable of making damping by changing the damping characteristic according to the amplitude of vibration. CONSTITUTION:The first vibration-proof member 4 for damping the high- frequency small-amplitude vibration is laid extending over a link outer cylinder 2 and a link rod 3. The second vibration-proof member 5 for damping the low- frequency large-amplitude vibration is fitted only to the link rod 3. When the high-frequency small-amplitude vibration is generated, the vibration is damped by the damping function of the first vibration-proof member 4 and the dynamic damper function of the second vibration-proof member. When the low-frequency large-amplitude vibration is generated, the displacement of the second vibration-proof member 5 caused by the amplitude is regulated and the vibration damping function of the second vibration-proof member 5 is exhibited. |
