<p>One-piece plastic roller guide having a tubular body and two sets of three leaf springs projecting symmetrically from the root of the tubular body in opposite axial directions. At the free end of each set of leaf springs, the inner diameter of the roller guide is slightly less than the diameter of the fixed cylindrical pin on which it is mounted. This slight interference between the springs and the pin assures continuous contact between the roller guide and pin without unduly inhibiting rotation.</p> |
