PROBLEM TO BE SOLVED: To provide a vibration reducing structure for piping allowing lightening of a weight and having a damping effect against vibrations having a plurality of resonance frequencies and to provide an inexpensive vibration reducing structure for piping simplified in structure with a small mounting space and resistant to penetration of water or dust from the outside. SOLUTION: In this vibration reducing structure for piping, an annular weight 3 is mounted on the outer surface of a pipe 1 with a clearance, and a cover 5 for covering the weight 3 is provided on the pipe 1.
