Abstract: A small-diameter part in the vicinity of a center of a bellows portion in an axial direction has a smaller diameter. A tip end of the small-diameter part contacts at a point A with an outer peripheral face of an interlock pipe. The interlock pipe vibrates with using the point A and points B in both ends as fulcrums. The addition of the point A reduces distance between the fulcrums. In accordance with this reduction, deflection amount of the interlock pipe is reduced and vibration amplitude of the interlock pipe is decreased. Therefore, the interlock pipe does not contact with the bellows portion so that troubles such as noises can be prevented from occurring.
