Vibration damping mount and metal heat shield

Abstract

The present invention provides a vibration damping mount with which a vibration damping action is improved and also provides a metal heat shield with which a sound insulation performance is improved. The vibration damping mount includes: a substantially annular damping member that has an insertion hole, through which the bolt to be attached to an attachment boss is inserted, and externally surrounds the bolt; a grommet that includes a first retaining section for retaining a heat shield, 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 attachment boss side; and a collar member that 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.

       3 . A vibration damping mount that is arranged between plural object members and damps transmission of a vibration from one object member, which is a vibration source, to the other object member, the vibration damping mount comprising: 
 damping members stacked one on top of another and formed of an iron alloy, the damping member having a plate configuration including an insertion hole for accepting a screw member to be attached to the one object member the damping members having films formed on surfaces thereof, the films containing at least a metal or a metal compound with an ionization tendency closer to that of aluminum than that of iron, and the damping members nipping the other object member near an outer peripheral portion thereof so as to be displaceable in a radial direction; and    a collar member that includes a pair of flange sections which are arranged between the screw member and the damping members so as to be displaceable in a radial direction and an axial direction with respect to the damping members, the flange sections nipping the damping members from both sides in an axial direction with gaps formed on both the sides, and the collar member including a coupling section for coupling the pair of flange sections.
