CONSTITUTION: A vibration proof device (200) for a post structure comprises a plate (220), a movable member (240), washers (231, 232), a weight part (250), and a vibration absorbing member (260). The movable member includes a settling part (241) settled on the top of the plate and an extension rod (242) shaped into a coil spring. The weight part is formed on the bottom of the extension rod. The vibration absorbing member is positioned between the weight part and a post structure. |
