Patent ID: 7464918

Claim:
A liquid sealing type vibration control device comprising: a first attachment fitting; a second attachment fitting; a vibration isolating base body made of rubber-like elastic material interconnecting these; a diaphragm attached to the second attachment fitting to form a liquid sealing chamber between the vibration isolating base body and itself; a partition body comparting the liquid sealing chamber into a first liquid chamber on a side of the vibration isolating base body and a second liquid chamber on a side of the diaphragm; and an orifice putting the first liquid chamber and the second liquid chamber into communication with each other, the partition body including an elastic partition membrane and a pair of lattice members regulating a displacement amount of the elastic partition membrane from both sides thereof, wherein the elastic partition membrane is provided, on both faces thereof, with respective rib groups in a projecting manner; the rib groups each consist of a plurality of first ribs and a plurality of second ribs mingled with one another; the first ribs are arranged on a surface of the elastic partition membrane so as to be capable of surrounding lattice holes every lattice hole or a plurality of lattice holes and the second ribs are arranged on the surface of the elastic partition membrane in a distributed fashion; the first ribs are set in such a height dimension that top parts of them can be situated apart from the lattice members; and the second ribs are set in such a height dimension that top parts of them abut on the lattice members and are set in a smaller rib width than the first ribs.
