Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vibration control device for structure such that the length of a cable can be suitably set and vibration control effect by the whole device including a second mass damper can be suitably obtained.SOLUTION: One end part of a support member 2 is connected to a support F supporting a structure B, and a first mass damper 3 which converts input displacement into rotary motion of a first rotary mass is connected to an upper end of the structure B and the other end of the support member 2. Further, a first pulley 8 is connected to an upper end of the structure B, and a second pulley 9 is fitted to the other end of the support member 2. Further, a cable 5 has its one end connected to the other end of the support member 2 and is also wound around the first and second pulleys 8, 9, and a second mass damper 4 which converts the input displacement into rotary motion of a second rotary mass is connected to the upper end of the structure B and the other end of the cable 5.
