Abstract

PURPOSE:To facilitate support of a partition by parting the space of the interior of a mount rubber and forming a partition plate having an orifice with high elastic plate curved and extruded spherically toward either of chambers above or below the partition. CONSTITUTION:Between both base plates 1, 2, a mount rubber 4 provided with a space 3 therein is inserted and fixed. The space 3 is parted by a partition 6 to form a fluid chamber 8 and a secondary chamber 10. The partition plate 6 is made of a thin wall of high elasticity and the central portion 6b of the partition is made curved and extended spherically toward the chamber 8 as well as the partition has an orifice 5 communicating the chambers 8, 10. Consequently, the partition plate 6 is adapted to also bend upward as shown in chain lines due to elastic deformation of the central portion 6b. Size and elasticity of the partition plate 6 is set in such a way that the volume of a region defined between the upper limit and lower limit deformations of the partition plate 6 is equal to the differential volume of the space 3 caused by expansion and contraction of the mount rubber 4 occurring due to input of fine vibration with a high frequency.
