Claims

[Scope of utility model registration request]

Two spring members made of a rubber-like elastic material that are approximately disk-shaped and made in the same shape are arranged symmetrically in the axial direction, and the outer peripheral ends of both spring members are fixed to a common case. The inner peripheral ends are connected to each other by a shaft member, a partition member having an effective variable area different from that of the spring member is disposed between the two spring members, and the outer peripheral end of the partition member is connected to the case. At the same time, the inner peripheral end is fixed to the shaft member, and the partition member has a substantially disk shape and has an orifice attached thereto, and a rubber-like elastic member disposed on the outer or inner periphery of the stopper member. 1. A vibration isolating device comprising: a sheet member made of wood, and wherein first and second liquid chambers between the two spring members partitioned by the partition member are filled with a working fluid.
