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.

       6 . 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 another object member, the vibration damping mount comprising: 
 a spacer that has a substantially cylindrical base section having an insertion hole, through which a screw member to be attached to the one object member is inserted, and a sliding section, which integrally continues outwardly in a radial direction of the base section and has a opposing sliding surfaces with a distance between the sliding surfaces in an axial direction decreasing with increasing outward distance in a radial direction of the sliding surfaces;    a nip member that is arranged outwardly in a radial direction of the spacer and includes a pair of nip pieces, which are arranged increasingly spaced apart from each other in the axial direction with decreasing inward distance in the radial direction, the pair of nip pieces being formed of a spring material which elastically nips the sliding surfaces of the sliding section of the spacer from sides opposed to each other, and said nip member being configured to define a clearance at least in the radial direction with respect to the spacer such that said nip member is radially displaceable relative to the spacer; and    a coupling member that includes a first retaining section for retaining an outer circumferential portion of the nip member, a second retaining section for retaining the other object member, and a coupling section for coupling the first retaining section and the second retaining section, the first retaining section, the coupling section, and the second retaining section being provided in this order from the one object member side.    
   
   
       7 . A vibration damping mount according to  claim 6 , wherein the sliding surfaces are flat taper surfaces tapering towards each other with increasing distance in the radial direction, a stepped portion elevated in the axial direction is formed at a boundary of the sliding section and the base section, and 
 said nip member has an elevated portion, which is engageable with the stepped portion at a time of displacement to an inside in the radial direction of the nip member, the elevated portion being is formed on an inner circumferential portion of said nip member and defining said clearance between said elevated portion and said stepped portion.
