PURPOSE:To achieve miniaturization, and to enhance durability by dividing a mass body into two divided mass bodies in the direction of a turning shaft, and forming an axially penetrated parts in the fitting circular plate, and connecting the inner circumferential parts of respective divided mass bodies with connecting members. CONSTITUTION:In a mass body 12, a first divided mass body 12a and a second divided mass body 12b are joined in the axial direction, and they are arranged on turning-shaft directional both sides of a fitting circular plate 11. In the inner circumferential part, the machine screws 19 and inserted through the inserting through holes 18b of respective fitting pieces 17b of the second divided mass body 12b are screwed into the tapped holes 18a of respective fitting pieces 17a of the first divided mass body 12a so as to be connected each other. Thus, miniaturization can be achieved, and a desired damping characteristic can be set, and a high durability can be obtained without being influenced by the aging deterioration of an elastic body. |
