Document Type and Number:
Japanese Patent JP2015147650
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rack vibration control device that prevents an increase in response in a vibration-control orthogonal direction, while preventing an increase in the complication and weight of the device.SOLUTION: A vibration control device 10 provided in a rack 2 includes a movable mass 30 that is supported in such a manner as to be slidable in a horizontal direction 1, and a damper 50 for suppressing sliding-direction displacement of the movable mass 30. The movable mass 30 comprises a first movable mass 33, and a second movable mass 37 that is loaded on the first movable mass 33. The second movable mass 37 is unmovable in the horizontal direction 1 and movable in a direction orthogonal to the horizontal direction 1, with respect to the first movable mass 33.
