Abstract
A fluid sealed type vibration insulating device provided with an actuator for generating an active supporting force. The vibration insulating support device includes a main fluid chamber defined by a cylindrical elastic support and a movable plate connected to a plate spring. The actuator moves the movable plate to change a dynamic spring characteristic and a damping characteristic of a fluid resonance system constituted by a mass of fluid in the orifice, the elastic support, and the plate spring. The plate spring elastically supports the movable plate so that the movable plate is displaced to change the volume of the fluid chamber. The plate spring includes a plurality of rectangular plate spring portions which are radially arranged.
