PURPOSE:To provide a damper whose operating range is wide, and which is in a compact size and a light weight. CONSTITUTION:A horizontal taking-out rod 5 is extendedly provided on a transfer rod C which is hung down from a structure A, and it is inserted into a housing 10 enclosing a viscous material 1, and also a rotary shaft 2 having coaxially a pinion 4 meshing with racks 6 formed on both side surfaces of the taking-out rod 5 is erectly provided on the both sides of the taking-out rod 5. Two rotary discs 3 installed on respective rotary shafts 2 are arranged so as to be laminated alternately, and the viscous material 1 is interposed in a clearance inside the rotary discs 3. When the taking-out rod 5 is displaced relatively in association with vibration of the structure A, vibration of the structure A is damped by viscosity resistance between the rotated rotary discs 3 and the viscous material 1.
