Patent ID: 7284748

Claim:
A vibration damping mount that is arranged between plural object members, which are coupled each other using a screw member, and damps transmission of a vibration from one object member, which becomes a vibration source, to the other object member, comprising: a substantially annular damping member that has an insertion hole, through which the screw member to be attached to the one object member is inserted, and is provided externally surrounding the screw member; a coupling member that has an insertion hole through which the screw member to be attached to the one object member is inserted, and includes a first retaining section for retaining the other object member, a second retaining section for retaining the damping member, and a coupling section for coupling the first retaining section and the second retaining section, the second retaining section, the coupling section, and the first retaining section being provided in this order from the one object member; a collar member that is arranged between the screw member and the damping member and includes a pair of flange sections, which nip the damping member from both sides in an axial direction with gaps formed on both the sides, and a coupling section, which couples the pair of flange sections each other and has a gap in a radial direction between the coupling section and the damping member; and wherein at least one of the coupling member and the collar member is formed of an aluminum alloy, the damping member is formed of an iron alloy, a film is formed on a surface of the damping member, and the film contains at least a metal or a metal compound having an ionization tendency closer to that of aluminum than that of iron.
