Vibration damping device

摘要

A vibration damping device including: first and second mounting members; a main rubber elastic body elastically connecting the two members; and a bracket member fit into the first mounting member. A projecting part projects outward from a circumference of the first mounting member, and includes a locking groove whose inner surface is covered by a rubber coating layer and has a locking part on its side wall inner surface. An engaging projection projecting from the bracket member is fit into the locking groove, and a projection tip surface of the engaging projection is abutted on a bottom wall inner surface of the locking groove. A side surface of the engaging projection is locked to the locking part so as to constitute a positioning member that positions the first mounting member and the bracket member to each other.
