PURPOSE:To bring large damping effect for all sorts of vibration by interposing an elastic body of high hardness between the first vibration-proof rubber and the second vibration-proof rubber. CONSTITUTION:In the vibrations transmitted from a road surface and the like via a support panel 14, the vibration in the up and down direction is received by the elastic deformation of the first vibration-proof rubber 15 and the second vibration-proof rubber 16, and the vibration in the right and left or front and rear direction is received by the compressive deformation of a vibration-proof rubber 20 having high hardness. Thus, since the spring constant of the vibration- proof rubber 20 is higher than that of the first or the second vibration-proof rubber 15 or 16, the damping effect for the vibration in the right and left or front and rear direction is enhanced, enabling the damping effect to increase. |
