Abstract: A vibration damping bushing including: an inner axial member; an outer cylindrical member through which the inner axial member is inserted; a main rubber elastic body elastically connecting the two members; and a stopper member that is fitted onto the inner axial member as a component of a first stopper mechanism that limits relative displacement of the inner axial member against the outer cylindrical member to one side in an axial direction. The inner axial member is formed with a latching depression that opens toward an outer periphery thereof, and the stopper member is provided with a latching piece that protrudes outward in the axial direction. The latching piece is engaged with the latching depression so as to provide a slipping out prevention mechanism for preventing the stopper member from slipping out from the inner axial member.

Abstract: An edge is provided between an outer peripheral part of a diaphragm and a frame. The edge includes a concave part which is formed along the outer peripheral part of the diaphragm and which includes a recess. The concave part is comprised of a first material. A second material is filled in a part of the recess and has lower density than the first material.
