PURPOSE:To provide a vibrationproof structure which can prevent the vibration of a beam and a frame which is suspended on the beam and is applied with a cyclic force. CONSTITUTION:The first spring means 4 is interposed in a suspension member 3 in order to prevent the transmission of vibration to a beam 1 from a frame 2, and an additional mass body 6 is suspended through the second spring means 5 from the beam, and the work executed by a cyclic force is absorbed as the vibration of the additional mass body. Accordingly, in this vibrationproof structure, the first spring means as the vibration insulation is interposed between the beam and the frame, and the additional mass body as dynamic damper and the second spring means are installed on the frame. |
