Abstract:
A liquid sealed type vibration isolator comprising:two metal fixing members for attachment to a vibration generating member and a support member; a vibration isolating elastic base member interposed between the two metal fixing members; a body member connected to the vibration isolating elastic base member; a diaphragm disposed opposed to the vibration isolating elastic base member to define a liquid chamber between the vibration isolating elastic base member and the diaphragm in conjunction with the body member; and a partition disposed in the body member and dividing the liquid chamber into a first liquid chamber and a second liquid chamber, the partition having an outer circumferential portion defining an orifice in conjunction with the body member, the outer circumferential portion being bent to a substantially L-shaped cross section so as to define to an inner circumferential surface and a bottom surface of the orifice; wherein the outer circumferential portion has an upper end section extended upward and inserted into an annular positioning groove formed in a liquid chamber-side circumferential edge portion of the vibration isolating base member, whereby the partition is positioned.
