PROBLEM TO BE SOLVED: To provide a vibration control device for a building structure of a novel structure capable of easily performing the setting of a tuning frequency and arranging work by easily adjusting mass of mass members and easy in carrying-in and arranging work of the mass members in the vibration control device exhibiting a vibration control effect to horizontal directional vibration by being installed in the building structure. SOLUTION: Adjusting spaces 16, 88, 92, 96 are formed in mass members 12, 86, 90, 94, and an additional mass member 17 can be housed in the adjusting spaces 16, 88, 92, 96 to thereby easily adjust mass of the mass members 12, 86, 90, 94 in a vibration control device 10.
