ABSTRACT:
A vibration damping device, including: first and second mounting members spaced apart from one another; an elastic body interposed between and connecting the two mounting members; a diaphragm cooperating with the elastic body to define therebetween a fluid chamber; and a partition structure including a partition member and a flexible movable plate disposed in a central opening of the partition member so as to divide the fluid chamber into primary and auxiliary fluid chambers communicating through an orifice passage, wherein the movable plate has a primary-fluid-chamber-side recess which is formed in one of opposite surfaces thereof on the side of the primary fluid chamber and an auxiliary-fluid-chamber-side groove in the other surface located on the side of the auxiliary fluid chamber so as to be positioned radially outwardly of the recess and which continuously or discontinuously extends in the circumferential direction.
