Claims

[Scope of utility model registration request]

An annular elastic member 3 is interposed between the boss portion 1 attached to the engine unit side or the vehicle body side and one end side of the cylindrical body 2, and The diaphragm 5 is surrounded by the diaphragm 5, the cylinder 2, the annular elastic member 3, and the boss 1 by fixing the plate 4 to be attached and horizontally installing the diaphragm 5 in the space surrounded by them. A partition that forms a liquid chamber 8, has a thin inner part surrounded by a thick peripheral edge, and is provided with an orifice 7 that communicates with the peripheral edge in the thickness direction, and is entirely made of an elastic material. A plate 6 is interposed in the liquid chamber 8, and the liquid chamber 8 is connected to the first damper liquid chamber 8A facing the annular elastic member 3 and the orifice 7 to the first damper liquid chamber 8A.
A vibration isolating rubber device characterized in that it is divided into a second damper liquid chamber 8B communicating with the diaphragm 5 through the diaphragm 5, and a second damper liquid chamber 8B facing the diaphragm 5.
