Abstract
A vibration damping apparatus actively damping vibration of a vibration source by adding vibration to the vibration source includes a vibrational state detecting means and a vibrator including a magnetic pole, a coil, and a controlling means, and the vibrator adds vibration to the vibration source by controlling a current-supplied state of the coil to vibrate the coil and the magnetic pole relatively, wherein the controlling means selectively switches a vibration generating mode and a regenerative mode based on the vibrational state of the vibration source, the vibration is added to the vibration source to damp the vibration of the vibration source in the vibration generating mode, and regenerative current is caused by an electro motive force generated at the coil by the vibration of the vibration source to flow into a regenerative resistor in the regenerative mode.
