<P>PROBLEM TO BE SOLVED: To provide a piping vibration damping device having a simple structure and capable of withstanding a use under the high-temperature environment. <P>SOLUTION: The piping vibration damping device 1 includes a fixing tool 2 which is mounted to the outer circumference of a pipe P to be vibration-damped, a laminated leaf spring 3 with its one end fixed to the fixing tool 2, and a weight 4 mounted to the other end of the laminated leaf spring 3. The laminated leaf spring 3 is formed by laminating a plurality of flat springs 7, and has a fastening mechanism 8 for adjusting a friction force between the flat springs by controlling contact pressure between the flat springs 7 at an intermediate part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
