Abstract
A liquid-in vibration-isolating device, used to support a vibration generating source such as a vehicle engine for the purpose of vibration isolation, prevents hitting sound or adsorption of a diaphragm due to abutment against a partition member and proper functioning of the device is maintained, without increasing the volume of sub-liquid chamber on the diaphragm side. The device includes a cylindrical body fitting and a boss fitting connected via a vibration isolating substrate. A diaphragm is provided on an opening portion at the upper extremity, being partitioned into a main liquid chamber on the vibration isolating substrate side and a sub-liquid chamber on the diaphragm side by means of a partition member. Both liquid chambers are connected through an orifice of the outer circumferential portion. Multiple convex portions are provided for restraining the diaphragm from abutting against the partition member.
