To provide a pipe vibration damping structure capable of providing the sure vibration damping effect more than a case of only a flexible member, relatively inexpensive in manufacturing cost, capable of absorbing a dimensional tolerance even if there is the dimensional tolerance, restraining a weight increase in a pipe, and superior in space-saving performance and installation-removal performance.
In a vibration damping member 14, a minimum inside diameter dimension L1 of an inside space S is smaller than an outside diameter dimension D of the flexible member 10, and a maximum inside diameter dimension L2 of the inside space S is larger than the outside diameter dimension D of the flexible member 10. Thus, in installation with the flexible member 10, the vibration damping member 14 includes a contact part 17 for contacting with the flexible member 10, and an isolation part 18 positioned between the contact part 18 and itself and not contacting with the flexible member 10. The inside space S of the vibration damping member 14 is defined so that its force becomes a degree that the vibration damping member 14 relatively loosely fastens the flexible member 10, while changing the force generated when the isolation part 18 is deformed in the installation with the flexible member 10, to force for pressing the flexible member 10 by the contact part 17.
