A vibration control apparatus (50) includes a first spring mechanism (3) to support a first object as part of a first system. To control vibration of the first object, a first actuator (4) applies a force to the first object via a command value generated by a first computing based on an output of a detection system. The detection system includes a second spring mechanism (23) to support a second object as part of a second system. A third spring mechanism (24) supports a third object as part of a third system. The first displacement detector detects displacement of the third object relative to the second object. The third object is prevented from being displaced relative to the second object. A second natural frequency of the second system is higher than a first natural frequency of the first system, and a third natural frequency of a third system is higher than the first natural frequency. |
