Abstract

PURPOSE:To constitute an apparatus with a small mass for a first movable mass requiring a small installation area by attaching a second vibration controller on the first movable mass. CONSTITUTION:Acceleration of a vibrating body 1 is detected by an accelerometer 8, and vibration level is determined by a controller 9. When the vibration is large, a first large-sized movable mass 4a of a first vibration controller 10 is driven by a first actuator 3a while a second movable mass 4b is fixed. If the vibration level is low on the other hand, the first movable mass 4a is fixed while the second small-sized movable mass 4b is driven by a second actuator 3b thereby damping of vibration due to external force Fex is made. In this case, a second vibration controller 11 is mounted on the first movable mass 4a so that the mass of the first movable mass 4a can be reduced by the mass of the second vibration controller 11. In addition, it is possible to decrease the installation area and height.
