PURPOSE:To make a device perform smoothly for a variation in the pressure receiving area of a fluid pressure receiving chamber, and secure a stable, low spring constant as well as to make high frequency vibrations absorbable in an efficient manner, in case of the above-captioned device that applies both spring characteristics and damping effects dependent on a fluid, to a mount rubber. CONSTITUTION:A reinforcing plate 8 is installed in a mount rubber 3 as set along the contour of a pressure receiving surface 7 of a pressure receiving chamber. At the reinforcing plate 8, there are provided with a lot of slits 8a in a radial direction, making a spring constant go down. In this way, deformation in the pressure receiving surface 7 is checked and a smooth variation in the pressure receiving area can be secured without raising the spring constant of the mount rubber 3, thus making the spring constant possible to become ideally low, and high frequency vibrations can be prevented without fail. |
