Abstract
A dish is placed in a circular opening about a spindle comprising a central collar. The dish comprises a ball bearing retained by a cage. There is placed inside the dish, concentrically with respect to the spindle, two half-cams separated at the upper ends thereof by an arcuate spiral spring, while the two half cams have lower portions defining a space in which can move a finger rigidly connected to said central spindle containing an articulation control shaft so to form an assembly. The assembly enables, when mounted, passing over hard points by a displacement of the two half-cams one toward the other while compressing the spring under effect of a thrust imparted by the finger of one of the two half-cams. A casing is rigidly connected to the mobile flange for retaining the aforementioned member assembly while a lower and hollow guide rigidly connected to the fixed flange maintains a lower portion of the casing.
