Title:
VIBRATION ISOLATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/142215
Kind Code:
A1
Abstract:
In a vibration isolation device (10), a connection rod (12) penetrates a cavity (104)
in a rubber elastic body (44) and the inner peripheral side of a body plate (14),
and further, a stopper rubber (98) fixed to the outer peripheral side of a rod body
(13) of the connection rod (12) is placed in the cavity (104) of the rubber elastic
body (44). The construction above enables the rod body (13) to be placed in the
axial direction of the connection rod (12) in a manner superposed over the rubber
elastic body (44), and as a result, a stopper mechanism is formed by a stopper member
(96) fixed to the rod body (13) of the connection rod (12). An increase in the axial
dimension of the device is suppressed, and the stopper mechanism prevents excessive
displacement of the connection rod (12) in the direction perpendicular to the
axis of the rod and prevents extension of the axial dimension of device.
