VIBRATION PROOF SUPPORTING DEVICE

Japanese Patent JP3412500

B2

PROBLEM TO BE SOLVED: To provide a vibration proof supporting device which generates high supporting force by employing a large effective pressure receiving area and also to provide a sealing member having enhanced durability.
SOLUTION: The outer periphery part 86a of a sealing member 86 covers the entire region of the curved surface-formed inner periphery surface of a sealing ring 72 for fixation. The inner periphery part 86b covers the outer periphery surface, the top part, and the inner periphery surface of a curved surface-formed rib 80b for fixation. An extended sealing part 86C for covering the upper surface of the partition wall part 80c of the rib is continuously formed on the inner periphery part of the sealing member. A toroidal recessed part 86d is formed on the upper surface at the position approaching the outer periphery part of the sealing member. In the absence of the electromagnetic force of an electromagnetic actuator, a movable member 78 is displaced as far as the neutral position providing balance to the bearing power of a plate spring 82 and the magnetic force of a permanent magnet 52c. Where, the sealing member has no elastic deformation on displacing the movable member as far as the neutral position. The fixing position between a partition-forming member and the sealing ring is set so that the movable member may have the elastic deformation on upwardly or downwardly displacing the movable member.
