Abstract

PURPOSE:To damp the vibration of a pillar by providing the support of the pillar with a ring-shaped weight grooved on the upper face to keep a plurality of balls to be dashed to the pillar via a coil spring or directly. CONSTITUTION:When a pillar 1 is vibrated by an earthquake or other external forces, in the case of a large amplitude, the pillar 1 is dashed to a weight 5 for damping its vibration, and in the case of a small amplitude, it is not dashed to the weight 5, but dashed to a plurality of balls 7 placed in a groove 6 provided on the upper face of the weight 5 for damping its vibration.
