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 conical-shaped elastic support and a movable construction part. The movable construction part is constituted by a partition wall and a magnetic path member which is fastened to the partition wall through a clearance spacer. Therefore, a clearance is formed between the partition wall and the magnetic path and a plate spring is installed in the clearance to support the movable plate against the magnetic force of a permanent magnet. The partition wall has an internal thread hole to be bolted. The magnetic path has a hole with one opening diameter larger than another opening diameter for inserting a bolt. The bolt has a dish-shaped bolt head. If a center of the hole is off to the side of the center of the partition wall's hole, any edge point of the bolt head contacts any surface of the inner hole and pushes.

Abstract: A vibration insulating apparatus and a vibration insulating method disclosed herein is preferably applied to a vibration insulating mount disposed between a vibrating body and a mounting body. Here, the vibration insulating mount comprises a fluid chamber filled with fluid, an elastic support partly defining the fluid chamber, a movable member partly defining the fluid chamber, a resilient member resiliently supporting the movable member, and an actuator generating displacing force for the movable member according to a drive signal so as to change volume of the fluid chamber. Also, a reference signal indicative of a vibrating condition of the vibrating body and a residual vibration signal indicative of a residual vibration of the mounting body are generated.
