摘要： This invention relates to a vibration-damping apparatus (dynamic damper) for damping vibration in tower-like structures and multistored buildings. More specifically, in a pendulum type vibration-damping apparatus comprising a weight (1), a spring (9), a damper (8), suspension members (2, 3, 4) and a fitting frame (7), the present invention provides a vibration-damping apparatus characterized in that upper suspension frames (5, 6) and lower suspension frames (5', 6') each consisting of a quadrilateral are disposed between the fitting frame (7) and the weight (1), the upper suspension frames (5, 6) and the lower suspension frames (5', 6') are supported by four joint materials (5a, 5b) so as to suspend the weight (1) in multiple stages and the fitting angles of the lower suspension frame quadrilaterals with respect to the upper suspension frame quadrilaterals are made unequal lest the suspension members (2, 3, 4) overlap. In a dynamic damper consisting of a vibration system and an oil damper (8), the present invention provides also a vibration-damping apparatus characterized in that an oil damper (8) of the type whose damping force is proportional to the square of a speed beyond a certain speed level is employed.
