Title:
ANTI-VIBRATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/056329
Kind Code:
A1
Abstract:
In the present invention, when an insulator is non-circular, this non-circular shape is utilized to increase a spring ratio in an X-direction and a Y-direction. An insulator 16 is rectangular when seen in plan view, a pair of X-direction elastic walls 40 that face one another in the X-direction are short in the Y-direction and are thin, and an X-direction projected area is small. A pair of Y-direction elastic walls 42 that face one another in the Y-direction are long in the X-direction and are thick, and a Y-direction projected area is large. A second attachment bracket 14 is also rectangular and long in the X-direction when seen in plan view, and provided with a pair of X-direction restraint walls 60 that face one another in the X-direction and a pair of Y-direction restraint walls 62 that face one another in the Y-direction, the X-direction restraint walls 60 being low and the Y-direction restraint walls 62 being high. A first attachment bracket 12 is provided with a pair of X-direction restraint protrusions 50 that face one another in the X-direction and a pair of Y-direction restraint walls 52 that face one another in the Y-direction, the protrusion length of the X-direction restraint protrusions 50 being short enough to not overlap the X-direction restraint walls 60, and the protrusion length of the Y-direction restraint walls 52 being long enough to overlap with the Y-direction restraint walls 62.
