Abstract

A liquid-sealed vibration-proof device is constructed so that a partition dividing its interior into a main and a subsidiary liquid chamber comprises an orifice member having an orifice, a partition plate member provided subjacently in contact with the orifice member, and an elastomeric membrane interposed between a central plate section of the orifice member and the partition plate member. The elastomeric membrane includes a central plate-form portion held and pinched by the orifice and partition plate members, and a diaphragm portion extending outboard it to terminate at an open end which is slidably brought in pressure contact with an annular wall section of the orifice member. Openings are provided in the central plate section and the partition plate member holding and pinching the central plate-form portion, which is partly exposed to both chambers, as an elastic membrane capable of elastic deformation.
