PURPOSE:To enable the transmission of medium-high frequency vibration input to be reduced even without lowering a spring constant. CONSTITUTION:A body side member 4 fixed to a body is elastically supported to a spring support 3 fixed to the upper end part of a shock absorber rod 2A through a supporting elastic body 5, and permanent magnets 10, 11 are fixed to the spring support 3 and the body side member 4 in such a way as to generate resiliency mutually in the vertical direction. An electromagnet 12 is fixed to the body side member 4 in such a way as to surround the permanent magnet 11, and the magnetic force generated by the electromagnet 12 can be changed freely by a controller 15. |
