ABSTRACT:
Provided is a liquid sealing type vibration control device capable of sufficiently reducing strange sounds which comprises a first attachment fitting (1), a second attachment fitting (2), a vibration-isolating base body (3), a diaphragm (9), a partition body (12), and an orifice (25), the partition body (12) including an elastic partition membrane (15) and a pair of lattice members (17, 18). The elastic partition membrane (15) is provided on its both faces with rib groups (50) in a projecting manner, the rib groups (50) each consist of plural first ribs (51) and plural second ribs (52) mingled mutually, the first ribs (51) are set in such a height dimension that their tops can be situated apart from the lattice members (17, 18), and the second ribs (52) are set in such a height dimension that their tops abut on the lattice members (17, 18) and in a smaller rib width than the first ribs (51).
