ABSTRACT:
In a transmission joint for rotating at high speed, a sealing device ensuring the retention of the lubricant comprises a bellows 9 of an elastomer and having an end wall 21 which is oriented radially and terminates in a heel portion 13 gripped in an annular groove 8 provided at the free end of a cap 4 surrounding one of the elements of the joint. In this way, there is obtained a minimum overall axial size of the joint and a good performance notwithstanding the effects of centrifugal force.
