ABSTRACT:
This invention relates to a vibration-preventing rubber device in which a partition wall having a hub is positioned outside an inner cylinder and is interposed between an upper plate and a lower plate which are connected to the inner cylinder. An upper vibration-preventing rubber member is interposed between the partition wall and the upper plate and cooperates with the partition wall and the upper plate to define an upper damper liquid chamber. A lower vibration-preventing rubber member is interposed between the partition wall and the lower plate and cooperates with the partition wall and the lower plate to define a lower damper liquid chamber. The upper damper liquid chamber communicates with the lower damper liquid chamber through an orifice. The orifice is formed from a long curved pipe in the shape of a helix or the like.
