Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vibration control device which is capable of being installed not inside a frame surface of a building but outside the frame surface, has no need of extending a separate member such as a reinforcement frame from the frame surface to the outside as in a conventional earthquake strengthening technology, and allows similar vibration control effects to be expected.SOLUTION: This vibration control device is installed on a frame surface P of a frame constituted of columns and beams of a structure, a damper 10 is disposed so as to be projected in a vertical direction from the frame surface at a center junction 14 among three junctions 11, 14 and 22 of the columns and the beams existing in a diagonal direction of the frame surface, a pair of brace members 1 and 2 are disposed between the junctions on both sides and a projected distal end of the damper to configure a toggle mechanism on the outer surface of the frame surface, and when the frame is displaced in the vertical direction of the frame surface at the respective junctions due to vibrations by an earthquake or the like, energy is absorbed by the damper disposed at the center junction.
