PROBLEM TO BE SOLVED: To provide anti-looseness fastener for preventing looseness of a nut in a vibration reduction stopper structure of a vibration-proof table.SOLUTION: An anti-looseness fastener comprises a first holding body constituted by a pair of supporting plates extended to be spaced apart only by a substantially same distance as a distance between the two faces opposite in parallel to an outer periphery of a nut in a horizontal direction,second holding body forming the substantial same shape as that of the first holding body, and a connector for connecting an end part of one of the supporting plates constituting the first and second holding bodies. This vibration reduction stopper structure with anti-looseness fastener is characterized in that the first holding body and the second holding body hold two parallel opposing faces of upper nut of a pair of nuts of vibration reduction stopper structure from their sides, the second holding body holds the parallel opposing two faces of a lower nut from their sides, and these holding bodies are installed at the upper and lower nuts to cause a relative rotation of the pair of nuts to be prohibited. |
