PURPOSE:To prevent oscillation of an apparatus in such a manner that a link mechanism having support shafts which are equally spaced around a main shaft, as the starting point, of a main lever, is provided for suspending from the shafts vertical levers which are connected together through a transverse lever below the supporting shafts, and the apparatus is suspended from the transverse lever at the center thereof. CONSTITUTION:A link mechanism a, a', b, b' having support shafts 3, 3, 4, 5, 5, 6, 6 which are equally spaced around a main shaft 2, as the starting point, of a main lever 1 is arranged and weights W1, W1 are suspended from the support shafts 6, 6. Further, vertical shafts 7, 7 are suspended from the support shafts 5, 5 which are linked together through a transverse lever 9. An apparatus 10 having an arbitrary weight is hung from the center of the transverse shaft 9, thereby to make proof against or prevent oscillation. |
