PROBLEM TO BE SOLVED: To provide a dynamic vibration absorber D simplified in structure to reduce the weight and costs, miniaturized for wide use, and facilitated in the adjusting work. SOLUTION: This dynamic vibration absorber comprises a base member 1 to be fitted to a vibration controlled material, and a weight 3 connected to the base member 1 so as to be relatively moved in the x-y direction by a vibration control rubber 2. A truncated conic non-linear coil spring 4 is arranged between the base member 1 and the weight 3, intersecting the axis 4a thereof with the moving direction of the weight 3. Pre-compression force in the axial direction to be applied to the coil spring 4 can be continuously adjusted by an adjusting screw 6. Only one coil spring 4 is arranged corresponding to the position of the center of gravity of the weight 3. COPYRIGHT: (C)2008,JPO&INPIT
