PROBLEM TO BE SOLVED: To provide a vibration-resisting device which is relatively simple in constitution and capable of lowering a characteristic frequency of a vibration- resisting stand and enlarging damping. SOLUTION: In this vibration-resisting device having a vibration-resisting stand 10 and a support mechanism 12 for vibration-resistantly supporting the vibration-resisting stand 10, a magnet 22 is provided in which a magnetic pole 24 is arranged at both poles, and a yoke 26 is provided which forms a magnetic circuit which is arranged in opposed to at least one magnetic pole 24 of the magnet 22 at predetermined gaps G1, G2 and in which a magnetic flux emitted from the magnetic pole 24 is branched and passed to at least two directions through the gaps G1, G2 and is returned to the other pole 24 of the magnet 22. A damper device 20 is so installed that the gaps G1, G2 may differentially change in a branched direction accompanying a vibration of the vibration- resisting stand 10 to change the branch of magnetic flux. |
