PURPOSE:To provide a vibration absorbing device which can carry out the control of the displacement of a control plate accurately, and can reduce the power consumption. CONSTITUTION:When a force is transmitted to a plate 107 through a hydraulic pressure operating liquid in an operating chamber 115 from an external side, a specific current is let flow to a solenoid coil 113, and a magnetic pole is generated to a yoke 111 so as to apply a force same as the force applied to the operating chamber 1-15 and in the reverse direction, to permanent magnets 123a and 123b. Since the permanent magnets 123a and 123b are fixed to the plate 107, two forces of the same strength and in the reverse directions are applied to the plate 107, so as to balance each other. To a shell 105 connected to the plate 107 through a leaf spring 109, the force applied to the operating chamber 115 from the external side is never transmitted. |
