摘要:
A vibration damping device includes: a cylindrical first attachment member and a second attachment member; and an annular first elastic body and an annular second elastic body, wherein, a liquid chamber is formed between the elastic bodies, elastic division walls that divide the liquid chamber into a plurality of pressure receiving liquid chambers are arranged, wherein the elastic division wall is joined to the first elastic body, and is also in abutment with the second elastic body, wherein the second attachment member is divided in the axial direction into: a first divided body to which an inner peripheral edge portion of the first elastic body is joined; and a second divided body to which an inner peripheral edge portion of the second elastic body is joined, and wherein the inner peripheral edge portions of the elastic bodies are located side by side in the axial O direction.
