Claims

[Scope of utility model registration request]

A fixed magnet fixed to a support that supports the vibrating body, a floating magnet placed opposite to the fixed magnet and floatingly supported by a spring with respect to the support, and a direction of excitation force from the vibrating body. The magnetic polarity of either one of the two magnets is switched in accordance with the change in the magnets, and the attractive and repulsive forces between the floating magnets' and the fixed magnets are changed. A vibration isolating device comprising: a control device that controls the excitation force to offset the excitation force.
