PROBLEM TO BE SOLVED: To prevent an unusual noise caused in an idle orifice opening/closing member by heavy vibrations occurring when an engine starts and stops. SOLUTION: A main liquid chamber 6 enclosed by an elastic body member 3 and an auxiliary liquid chamber 10 enclosed by a diaphragm 11 are partitioned by partition member 5. Both liquid chambers are connected with a dumping orifice 7 and an idol orifice 8. The opening 9 of the idol orifice 8 is closed by the seat part 12 formed at the center of the diaphragm 11. The seat part 12 is driven to open and close with a solenoid 20, and opening state is maintained when an engine starts, idles and stops respectively. |
