PURPOSE:To display a vibration isolating function also against the low frequency large vibration width of an engine part due to the rolling of a hull by constructing the title device in such a way as to variate and regulate the damping force of a damper by the control signals of a circuit device receiving signals from a detector at the time of the generation of rolling. CONSTITUTION:Compressed air is fed to each air spring 3, the internal pressure of these air springs 3 is kept high, and by that resiliency, an engine part 1 is supported in the position of specific height. A damping force variable damper 4 has a normal value that is relatively small in its damping force and its rigidity is in the soft state when its damping force variating actuator 15 is under the control of a control circuit 17 and in the normal typical oscillating state of a hull. When the oscillation of the hull is detected from the information signals from a rolling detector 16 inputted into the control circuit 17, the control signals are sent to the actuator 15, and the actuator 15 is driven to control the damping force of the damper 4 such as to become larger than the normal value. |
