PROBLEM TO BE SOLVED: To provide a vibration-proof device for piping capable of reducing vibrations in piping by changing a total mass of a vibration-proof member by selectively inserting a plurality of test pieces having different masses. SOLUTION: A vibration-proof device for piping contains a vibration-proof member 1 for reducing vibrations in piping 2. The vibration-proof member 1 is equipped with a body 10, a piping inserting hole 11 formed in the body 10 and provided with the piping 2 thereinside, one or more test piece holes 12, 13, 14 in which one or more test pieces 16, 17, 18 having different masses are inserted while being formed in the body 10.
