发明名称 Vibration damping device
摘要 A vibration damping device including: an inner shaft member; a main rubber elastic body fixed to an outer circumference surface of the inner shaft member; and an outer bracket attached to an outer circumference surface of the main rubber elastic body. At least one locking projection formed to an inner circumference surface on a bracket main unit provided to the outer bracket is inserted and locked in a circumference direction in at least one locking groove formed on the outer circumference surface of the main rubber elastic body. The main rubber elastic body is held between axially opposed surfaces of an abutting protruding part formed on one axial end of the bracket main unit and a retaining protruding part formed on a press fit metal fitting press fit and fixed to another axial end of the bracket main unit.
