PROBLEM TO BE SOLVED: To provide a vibration damper device which causes no breakage even under fluctuation of temperature, surely and sufficiently shows specified vibration control effect, and reduces manufacturing cost by decreasing temperature dependency in equivalent rigidity and attenuation performance with combination of the existing various viscous bodies. SOLUTION: A rigid plate member 1 can be connected to one of opposed portions of structural frames. Rigid plate members 2, 2 can be connected to the other of the opposed portions and are arranged on both sides of the rigid plate member 1 in this thickwise direction in parallel to its axial direction or substantially in parallel thereto. Viscous bodies 3A, 3B having different characterstics are arranged between the plate member 1 and the plate members 2, 2, which viscous bodies have different temperature dependent balance in rigidity and attenuation performance.
