Abstract

PURPOSE:To stop vibration quickly by hanging a pendulum protruding at the center of the undersurface of a vibro-preventive table down through a hole provided in the table top plate, and attracting the table bottom plate and pendulum bottom with a magnet. CONSTITUTION:A table top plate 1 is provided with a number of small holes 2, and a hole 7 is bored in its center. A vibro-preventive table 4 is placed and fixed on the top plate 1 by a resilient member 3, and a pendulum 6 is protruded at the center to penetrate the hole 7 in the table top plate 1. A magnetic member 8 is fixed at the bottom, being faced to a magnet 10 of a table bottom plate 9. When any apparatus is placed on the vibro-preventive table 4, the pendulum 6 is retained weakly by the magnetic force in the hangdown position. When the apparatus 5 is oscillated slowly by wind pressure etc., air stream, wind pressure, etc., between the vibro-preventive table 4 and the table top plate 1 are absorbed in the abovementioned small holes 2, and no resonance will occur. Thus the vibration is stopped quickly by the resilient member 3 and the magnetic force.
