摘要： A vibration damping device including: a first attachment member and a second attachment member disposed apart from each other; and a main rubber elastic body connecting the first attachment member and the second attachment member, the main rubber elastic body being of a frustoconical-like shape having an outer peripheral surface whose diameter gradually increases from the first attachment member toward the second attachment member, the main rubber elastic body including a recess opening onto a center portion thereof on a large-diameter side that is a second attachment member side, and the main rubber elastic body that constitutes a bottom part of the recess integrally including a vibration-damping protrusion protruding into the recess.

摘要： A vibration damping device including a main rubber elastic body elastically connecting first and second mounting members. An upper portion of the main rubber elastic body constitutes a small-diameter portion to which the first mounting member is bonded, while a lower portion thereof constitutes a large-diameter portion to which the second mounting member is bonded. The first mounting member includes an inner recess opening onto an outer circumferential surface thereof, and the small-diameter portion of the main rubber elastic body is bonded to the inner recess. The main rubber elastic body has an outside diameter dimension made larger at a portion bonded to the inner recess than an outside diameter dimension of the first mounting member at a lower side than the inner recess such that the small-diameter portion of the main rubber elastic body is thick-walled by being bonded to the inner recess.

摘要： A fluid-filled vibration damping device including: a first mounting member; a second mounting member; a main rubber elastic body elastically connecting the first and second mounting members; a pressure-receiving chamber whose wall is partially constituted by the main rubber elastic body; an equilibrium chamber whose wall is partially constituted by a flexible film, the pressure-receiving chamber and equilibrium chamber being filled with a non-compressible fluid; and an orifice passage which connects the pressure-receiving chamber and the equilibrium chamber to each other. A turbulence generating part is formed in a middle portion of the orifice passage in a length direction causing turbulence to be generated depending on a flow rate of a flowing fluid.

摘要： A fluid-filled vibration damping device including: first and second mounting members elastically connected by a main rubber elastic body; a tubular fitting member externally slipped around the second mounting member and drawn so as to be externally fitted thereto in a fluid-tight manner; a sealing rubber layer fixed to at least one of an outer peripheral face of the second mounting member and an inner peripheral face of the tubular fitting member so as to be compressed therebetween about an entire circumference; and at least one pressure-relieving lip protruding from the sealing rubber layer and extending toward openings of the second mounting member and the tubular fitting member so as to be pressed against one of the outer peripheral face of the second mounting member and the inner peripheral face of the tubular fitting member in a direction of protrusion.
