Abstract

A vibration-damping support device including: an inner shaft member to be attached to a first connection target; upper and lower mount rubbers externally fitted onto the inner shaft member; and upper and lower restraining members bonded to the upper and lower mount rubbers respectively and configured to be superposed against the second connection target. The upper and lower restraining members are configured to project to a peripherally inside of an opening edge of a mounting hole of the second connection target so that the upper and lower restraining members overlap with each other as viewed in axial direction there. The lower mount rubber includes a slot extending annularly on its outer periphery and an inner peripheral convex part projecting inward from an inside of the slot so as to have a curved shape that is convex inward at the inside of the slot.

First claim

What is claimed is:

1 . A vibration-damping support device comprising:
an inner shaft member configured to be attached to a first connection target; an upper plate projecting peripherally outward from a first end of the inner shaft member on a side of the first connection target; an upper mount rubber externally fitted onto the inner shaft member and configured to be disposed between opposed faces of a second connection target and the upper plate; a lower plate projecting peripherally outward from a second end of the inner shaft member, the second end being configured to project from a mounting hole of the second connection target to an opposite side from the first connection target with the inner shaft member inserted into the mounting hole; a lower mount rubber externally fitted onto the inner shaft member and configured to be disposed between opposed faces of the second connection target and the lower plate; an upper restraining member bonded to the upper mount rubber and configured to be superposed against the second connection target so as to project to a peripherally inside of an edge of an opening of the mounting hole; and a lower restraining member bonded to a portion of the lower mount rubber to be superposed against the second connection target, the lower restraining member being configured to overlap with the second connection target as viewed in axial direction, wherein the lower restraining member is configured to project to the peripherally inside of the edge of the opening of the mounting hole so that the lower restraining member and the upper restraining member overlap with each other as viewed in axial direction at the peripherally inside of the edge of the opening of the mounting hole, and the lower mount rubber includes a slot that opens onto an outer peripheral surface thereof and extends annularly in a circumferential direction so as to make the lower mount rubber thin in an axis-perpendicular direction at an inner peripheral side of the slot, and an inner peripheral convex part that projects peripherally inward from the inner peripheral side of the slot so that the lower mount rubber has a curved shape that is convex peripherally inward at the inner peripheral side of the slot.

2 . The vibration-damping support device according to claim 1 , further comprising: an upper rubber layer configured to be disposed between superposed faces of the upper restraining member and the second connection target; and a lower rubber layer configured to be disposed between superposed faces of the lower restraining member and the second connection target.

3 . The vibration-damping support device according to claim 1 , further comprising a cushioning rubber provided between the lower restraining member and the inner shaft member.

4 . The vibration-damping support device according to claim 1 , wherein the upper restraining member includes an insertion part configured to be inserted into the mounting hole so as to overlap with the lower restraining member as viewed in axial direction.

5 . The vibration-damping support device according to claim 4 , wherein the insertion part is covered by a covering rubber.

6 . The vibration-damping support device according to claim 1 , wherein the upper restraining member and the lower restraining member are superposed so as to be remote from each other in the axial direction at the peripherally inside of the edge of the opening of the mounting hole.
