A valve member formed of an elastomeric membrane for opening and closing a second orifice flow passage is mounted on a partition element such that the valve member is arranged orthogonal to the flow direction of the second orifice flow passage. A valve portion for closing openings of the second orifice flow passage due to flexural deformation of a flexible membrane portion caused by liquid flow in the second orifice flow passage is arranged on the flexible membrane, and communication holes for bring the second orifice flow passage into communication are formed in the flexible membrane portion.
