Abstract
A vibration-damping device having a first and a second mounting member elastically connected together by means of a main rubber elastic body; a resin bracket of generally tubular shape fastened fitting externally onto said second mounting member; and a rubber stopper having a through-hole formed in its basal end portion and supported by means of an engaging recess of the resin bracket. An inside width dimension of the engaging recess is wider at a bottom side portion than an opening portion so that an anchor shaped basal end portion of the rubber stopper fits inserted within said engaging recess, and the through-hole in the basal end portion of the rubber stopper is filled with the retaining resin element.
Claims7
A vibration-damping device for elastically connecting two components in a vibration damping fashion, said device comprising:
- a first mounting member fixable to one of the two components;
- a second mounting member of generally tubular shape fixable to an other of the two components, the first mounting member being disposed spaced apart from a first open end of the second mounting member;
- a main rubber elastic body elastically connecting the first and second mounting members together;
- an outer bracket of generally tubular shape fastened fitting externally onto said second mounting member so that the second mounting member is mounted via said outer bracket onto the other of the two components, the outer bracket comprising a resin bracket fabricated of synthetic resin that includes:
- an engaging recess at a first axial end portion thereof;
- an integrally formed flange portion at an other axial end portion thereof with a fastener fitting for fastening the resin bracket to the second mounting member being fastened inserted within said flange portion;
- and a retaining resin element integrally formed therewith;
- and
- a rubber stopper having a through-hole formed in a basal end portion thereof and supported by means of said engaging recess of the resin bracket,
- wherein an inside width dimension of the engaging recess is wider at a bottom side portion than an opening portion so that the basal end portion of the rubber stopper fits inserted within said engaging recess, and the through-hole in the basal end portion of the rubber stopper is filled with the retaining resin element.
