Abstract
A liquid-filled vibration absorbing device including a vibration absorbing base of rubber interposed between a holding cylinder of a lower mounting metal fixture and an upper mounting metal fixture. An annular member is fixed on the outer circumferential portion of the lower portion of the vibration absorbing base. A diaphragm is mounted on the lower end portion of an intermediate cylinder, and a partition member is mounted on the inner circumference of the intermediate cylinder. This intermediate cylinder is fitted at its upper portion in the cylindrical lower portion of the annular member and is fixed at the outer edge portion of its upper end on the flanged upper portion of the annular member, to form liquid chambers between the partition member, and the vibration absorbing base and the diaphragm and provide communication between the liquid chambers and through an orifice. The intermediate cylinder is press-fitted in the holding cylinder.
