<P>PROBLEM TO BE SOLVED: To provide a liquid sealing type vibration-proofing device capable of effectively and liquid-tightly sealing a limitation passage and stably exhibiting a targeted vibration damping function without incurring the increase of a manufacturing cost caused by enhancement of working accuracy of a passage forming member and disposition of a sealing member as a sub material. <P>SOLUTION: A partition wall 5 has a plurality of passage forming members 9, 10 and 11 contributing to partition of a limitation passage 8 surrounding the partition wall 5 one or more times in the peripheral direction thereof, the passage forming members 9, 10, 11 are formed by using materials having tensile moduli different from each other, flange parts 11a and 11b forming partition walls between the adjacent passage parts 8a of a limitation passage 8 are provided in one passage forming member 11, peripheral edges of the flange parts 11a and 11b are made to abut on the other passage forming members 9 and 10 and the passage forming member 11 having a small tensile modulus is subjected to crush deformation or compression deformation at the abutment place to attain liquid tight seal of the limitation passage 8. <P>COPYRIGHT: (C)2013,JPO&INPIT |
