が導入されピストン１１が上下方向に摺動する。When the vibration source 2 vibrates in the direction of arrow AB in FIG. 1, a variable load acts on the support base 3, and the first elastic body 6 is displaced. This displacement is detected by a displacement detector 13, and this detection signal is amplified by an amplifier 16, and then a low-pass filter 18 cuts high frequency vibration components in the amplified detection signal, and only very low frequencies are detected. A signal is extracted. A deviation is extracted from this signal with reference to the set voltage of the displacement setting device 3o, this deviation is added to the servo amplifier 20 and converted into a voltage value, and the servo valve 15 is driven by this voltage. Then, the oil passage of the servo valve 15 is switched in accordance with the voltage value, pressure oil is introduced into the upper hollow chamber 12A or the lower hollow chamber 12B divided by the piston 11, and the piston 11 slides in the vertical direction.

合された剛体とみなすことができる。In this case, since the piston 11 slides in the opposite direction to the displacement of the first elastic body 6, the displacement of the first elastic body 6 is absorbed by the vertical sliding movement of the piston 11. Therefore, the distance between the support base 3 and the installation base □4 is kept constant, and the support base 3 and the installation base 4 can be regarded as a rigid body combined into one body.
