Abstract
This invention relates to multiple mounting vibration-preventing device wherein a partition wall is interposed between an upper plate and a lower plate. An upper vibration-preventing rubber member is interposed between the partition wall and the upper plate so as to define an upper damper liquid chamber therebetween. A lower vibration-preventing rubber member is interposed between the partition wall and the lower plate so as to define a lower damper liquid chamber therebetween. The upper damper liquid chamber communicates with the lower damper liquid chamber through an orifice. An upper elastic film, disposed inside the upper vibration-preventing rubber member, has a portion spliced to the partition wall and its outer end part caulked to the upper plate. The upper damper liquid chamber is defined by the upper vibration-preventing rubber member and the upper elastic film. A lower elastic film, disposed inside the lower vibration-preventing rubber member, has a portion spliced to the partition wall and an outer end part caulked to the lower plate. The lower damper liquid chamber is defined by the lower vibration-preventing rubber member and the lower elastic film.
