<P>PROBLEM TO BE SOLVED: To provide a vibration measuring instrument capable of measuring the frequency of vibration generated in a structure without requiring a cable. <P>SOLUTION: A vibration measuring instrument 1 for a structure S includes three constituents: vibration bodies 13, amplitude display units 15, and housings 14. The plural vibration bodies 13 each have a spring 11 and a weight 12 suspended with the spring 11, and have mutually different natural frequencies. The amplitude display units 15 each visually display half amplitude of their respective vibration bodies 13 associated with displacement of the weights 12 in a vertical direction by vibration of the vibration bodies 13. Each of the housings 14 has a space for housing the vibration body 13 and the amplitude display unit 15, supports the spring 11 and the amplitude display unit 15, and is provided to the structure S. <P>COPYRIGHT: (C)2013,JPO&INPIT |
