| Zusammenfassung: | A damping device of an elevator capable of improving riding comfortableness in a car by efficiently damping vibration generated in the car. A filter means is used to lower the gains of those frequency bands other than a frequency band including the lower natural frequencies of a vibration isolating means elastically supporting the car among signals obtained from a vibration measuring means installed in the car. Thus, the riding comfortableness in the car can be improved by intensively using a movable weight and a drive means for damping the vibration caused by the low natural frequencies of the vibration isolating means. |
