PURPOSE: To secure a vibro-isolating pipe that is able to reduce a pitch of impact noise as well as to damp a pipe axial vibration so quickly. CONSTITUTION: This vibro-isolating pipe consists of a bellows, an interlock and the like. The interlock 3 is inserted into the bellows, wrapping itself on strip bodies 30a and 30b, and formed into a pipe form. Two hooks 32a and 32b of these adjacent strip bodies 30a and 30b constituting this interlock 3 are engaged with each other in a state of being conformed to each other, and they are slidable in the pipe axial direction. If being compressed in this pipe axial direction, the hook 32a of the strip body 30a on one side collides with an impact receiving part 31b of the strip body 33b on the other as sliding with the hook part 33b of the strip body 30b on the other. Since any vibration in the pipe axial direction is quickly damped by this sliding motion, the frequency of collisions is reduced and simultaneously the impact noise becomes lessened. As the impact receiving part 31b is at an angleθ(40 to 50 deg.) to the pipe axial direction, the impact noise becomes yet smaller.
