Abstract:
The present invention provides a vibration damping device which can enhance a vibration damping effect even in a case where a vibration damping target position and a vibration damping force generation position are different from each other. The vibration damping device includes a vibration detecting unit for detecting a vibration which is caused by a vibration generating source and is transmitted to a position at which the vibration is to be damped; a vibration application unit which generates a vibration damping force to cancel the vibration, and is provided at a position different from the position at which the vibration is to be damped; a vibration application command generating unit for outputting a vibration application command to generate the vibration damping force in the vibration application unit, based on the vibration detected by the vibration detecting unit; and a vibration application command correcting unit which imparts to the vibration application command, a reverse property of a vibration damping force transmission path including a vibration transmission property from a position at which the vibration application unit is mounted to the position at which the vibration is to be damped, and then outputs the vibration application command to the vibration application unit.
