ABSTRACT:
A tube has a deflection section to allow it to align between two bores which are substantially coaxial. The tube has an inner wall, an outer wall, a first end and second end. The first end of the tube rigidly connects to the first member. The second end of the tube slidingly extends into the bore of the second member. The deflecting section has circumferential inner and outer grooves. These grooves extend in from the inner and outer walls of the tube. Each of the grooves has an axial thickness that is much less than the distance between the grooves. The axial thickness is also less than the radial dimension between the base of each groove and the adjacent wall of the tube. This provides substantial rigidity to the deflecitng section, yet allows slight deflection.
