Abstract:
A vibration insulating mount disposed between a vibrating body and a mounting body, comprising:a fluid chamber filled with a fluid;an elastic support partly defining said fluid chamber and mounting said vibrating body;a multi-piece movable member partly defining said fluid chamber and capable of being displaced so as to change a volume of said fluid chamber, said multi-piece movable member including an inner wall forming member having an inner surface oriented toward said chamber and a separate outer magnetic path forming member which is fixed to an outer surface of the wall forming member which is oriented away from said chamber, the magnetic path forming member having a peripheral edge portion which is reduced in thickness relative to an adjacent portion of the magnetic path forming member;a supporting member supporting said multi-piece movable member; andan actuator opposed to the magnetic path forming member of said movable member which selectively generates a displacing force to displace said movable member with respect to said chamber.
