PROBLEM TO BE SOLVED: To provide a vibration isolation structure that suppresses a variation of vibration isolation performance associated with a temperature change of laminated rubber.SOLUTION: A vibration isolation structure has: laminated rubber which is arranged between a support and a supported body, and formed by alternately laminating a rubber plate and a rigid plate; a restraining member which moves in the lamination direction of the laminated rubber, and changes a region in which the laminated rubber is sheared and deformed; an actuator for moving the restraining member to the lamination direction; a temperature measuring means for measuring a temperature of the laminated rubber; and a control part which controls the actuator so that the restraining member may be moved to a direction in which the region in which the laminated rubber is sheared and deformed is reduced when the temperature of the laminated rubber measured by the temperature measuring means is high, and the restraining member may be moved to a direction in which the region in which the laminated rubber is sheared and deformed is increased when the temperature of the laminated rubber measured by the temperature measuring device is low. |
