A tripod element (18) trasmits by its arms (31) circumferential forces (F) to a female member-or bowl-through cups (20) and rolling needles. On the unloaded side of each arm, a clearance is produced between the arm and the corresponding support surface (24) of the bowl. Springs (16) act on the cups (20, 21) in such manner that this clearance is established between the complementary spherical surfaces of the arm and cup. The reserve of oil which is created therein will act as a shock absorber or damper in the case of reversal of the direction of the torque (C). Use in the elimination of shocks created by the reversal of the load on the joint.
