PROBLEM TO BE SOLVED: To obtain high damping force by reliably fixing a rocking piston, when a vibration exciting device stops its operation. SOLUTION: This liquid filing type vibration control device is composed of a first coupling member 91 mounted to the vibrating body side, a second coupling member 95 mounted to a member, etc., on the vehicle side, a rubbery insulator 8 interposed between the first coupling member 91 and the second coupling member 95 to shut off vibration from the vibrating body, a main chamber 6 and an auxiliary chamber 7 provided in series relative to the insulator 8 to be filled with liquid, an orifice 5 to run the liquid between the main chamber 6 and the auxiliary chamber 7, a partition member 3 to partition between the main chamber 6 and the auxiliary chamber 7, a vibration exciting device 1 comprising a rocking piston 11 provided in the middle of a communicating passage 35 connecting the main chamber 6 to the auxiliary chamber 7 and the like to excite the liquid in the main chamber 6 at a specific frequency, and a rotary actuator 2 to drive the vibration exciting device 1. |
