Abstract

Included are an outer attachment member 12, which is coupled to one of a vibration generator 16 and a vibration receiver, an inner attachment member 11, which is coupled to the other one of the vibration generator 16 and the vibration receiver, and an elastic body 13, which is positioned on the outer side of the inner attachment member 11 to couple the outer attachment member 12 and the inner attachment member 11. The outer attachment member 12 is disposed in at least one pair on the outer side of the elastic body 13, with the inner attachment member 11 being interposed between the at least one pair of outer attachment members 12. Each of the at least one pair of outer attachment members 12 includes an attachment surface 14, which is attached to the one of the vibration generator 16 and the vibration receiver.

First claim

The invention claimed is:

1. An attachment structure for a vibration-damping device, the vibration-damping device comprising
outer attachment members configured to be coupled to one of a vibration generator and a vibration receiver,
an inner attachment member configured to be coupled to another one of the vibration generator and the vibration receiver, and
an elastic body positioned on an outer side of the inner attachment member and coupling the outer attachment members with the inner attachment member, wherein:
at least one pair of the outer attachment members are disposed on the outer side of the elastic body, with the inner attachment member being interposed between the at least one pair of outer attachment members,
each of the at least one pair of outer attachment members includes an attachment surface that is configured to be attached to the one of the vibration generator and the vibration receiver, the attachment surface comprising:
a pair of opposing surfaces that are configured to hold and sandwich the one of the vibration generator and the vibration receiver between the pair of opposing surfaces; and
a wall surface connecting the pair of opposing surfaces, the wall surface extending in an axial direction between the pair of opposing surfaces,

the vibration-damping device is coupled to the one of the vibration generator and the vibration receiver via the at least one pair of outer attachment members of the vibration-damping device, by displacing the outer attachment members in an extending direction of the outer attachment members, while bringing the outer attachment members closer to each other toward the inner attachment member of the vibration-damping device, so as to mount the outer attachment members to the one of the vibration generator and the vibration receiver, and
the pair of opposing surfaces protrude outwardly from the wall surface in a radial direction of the inner attachment member.

2. The attachment structure according to claim 1 , wherein the outer attachment member comprises divided bodies, each of which separately includes a respective one of the pair of opposing surfaces.

3. The attachment structure according to claim 1 , wherein the attachment surface of the outer attachment member is disposed along a direction that is perpendicular to the axial direction of the inner attachment member.

4. The attachment structure according to claim 1 , wherein the attachment surface of the outer attachment member is disposed along a direction that is perpendicular to the axial direction of the inner attachment member.

5. The attachment structure according to claim 2 , wherein the attachment surface of the outer attachment member is disposed along a direction that is perpendicular to the axial direction of the inner attachment member.

6. An attachment structure for a vibration-damping device, vibration-damping device comprising
an outer attachment member configured to be coupled to one of a vibration generator and a vibration receiver,
an inner attachment member configured to be coupled to another one of the vibration generator and the vibration receiver, and
an elastic body positioned on an outer side of the inner attachment member and coupling the outer attachment member with the inner attachment member, wherein
at least one pair of the outer attachment members are disposed on the outer side of the elastic body, with the inner attachment member being interposed between the at least one pair of outer attachment members,
each of the at least one pair of outer attachment members includes an attachment surface that is configured to be attached to the one of the vibration generator and the vibration receiver,
the attachment surface comprises:
a pair of opposing surfaces that are configured to hold and sandwich the one of the vibration generator and the vibration receiver between the pair of opposing surfaces; and
a wall surface connecting the pair of opposing surfaces, the wall surface extending in an axial direction between the pair of opposing surfaces,

at least one of the pair of opposing surfaces is shaped to be inclined in a manner that a distance between the pair of opposing surfaces is continually increased from an inner end of the attachment surface to an outermost end of the attachment surface, and
the vibration-damping device is coupled to the one of the vibration generator and the vibration receiver via the at least one pair of outer attachment members of the vibration-damping device, by displacing the outer attachment members in an extending direction of the outer attachment members, while bringing the outer attachment members closer to each other toward the inner attachment member of the vibration-damping device, so as to mount the outer attachment members to the one of the vibration generator and the vibration receiver.

7. The attachment structure according to claim 6 , wherein the outer attachment member comprises divided bodies, each of which separately includes a respective one of the pair of opposing surfaces.

8. The attachment structure for the vibration-damping device according to claim 6 , wherein a surface of the one of the vibration generator and the vibration receiver configured to contact with the at least one of the pair of opposing surfaces is shaped to be inclined in correspondence with the at least one of the pair of opposing surfaces.

9. The attachment structure for the vibration-damping device according to claim 6 , wherein a surface of the one of the vibration generator and the vibration receiver configured to contact with the at least one of the pair of opposing surfaces is shaped to be inclined in correspondence with the at least one of the pair of opposing surfaces.

10. A vibration-damping device, comprising
outer attachment members configured to be coupled to one of a vibration generator and a vibration receiver,
an inner attachment member configured to be coupled to another one of the vibration generator and the vibration receiver, and
an elastic body positioned on an outer side of the inner attachment member and coupling the outer attachment members with the inner attachment member, wherein:
the outer attachment members comprise at least one pair of the outer attachment members disposed on the outer side of the elastic body, with the inner attachment member being interposed between the at least one pair of outer attachment members,
each of the at least one pair of outer attachment members includes an attachment surface that is configured to be attached to the one of the vibration generator and the vibration receiver, the attachment surface comprising:
a pair of opposing surfaces that are configured to hold and sandwich the one of the vibration generator and the vibration receiver between the pair of opposing surfaces; and
a wall surface connecting the pair of opposing surfaces, the wall surface extending in an axial direction between the pair of opposing surfaces, and

each of the pair of outer attachment members is attached in the state where each of the pair of outer attachment members is laid on its side, with an opening side thereof facing the outer side of the elastic body, and where each of the pair of outer attachment members protrudes into a circumferential wall of the elastic body, and
