Abstract

PURPOSE:To achive the excellent vibration isolating effect for the vibration having small magnitude as well as large magnitude of a pole, by providing an enclosed container equipped with a chamber containing the liquid at the position other than the fixed end of the pole where one or both ends are fixed while providing a flat member in said container. CONSTITUTION:When a pole 2 is vibrated by such as the earthquake, the kinetic energy of the ple 2 will eliminate through the viscous friction or inertia of the liquid itself, the friction of the friction flat boards 7, 8 between the liquid 5 and the flat members 7, 8 and the ball 9, the collision between the balls 9 and the collision between the flat members 7, 8 and the ball 9 thus to suppress the vibration of the pole 2. The viscous friction of the liquid 5 will function on the minute amplitude of the pole 2 resulting in the excellent vibration suppressing effect.
