摘要:PURPOSE:To exhibits a stable vibration control effect by interposing a flexible sheet between a spring portion and a damper inertia portion to work the stiff damper inertia portion as a uniform mass. CONSTITUTION:In a dynamic damper 1, a layer of a flexible sheet 5 is interposed between a spring a portion 3 and a damper inertia portion 4. The spring portion 3 is, for example, formed by an extrusion foam of rubber or a mold foam of urethane. As the flexible sheet 5, a plastics sheet such as soft vinyl chrolide or a rubber sheet is used. Accordingly, as the flexible sheet 5 is interposed between the soft foam 3 and mass members 4A, 4B, even if the mass members are separate, one-sided deformation and settling can be prevented, so that the mass members work as uniform damper inertia to exhibit a vibration control effect.
