Abstract
A universal joint having a trunnion cross adapted to be received in the arms of a pair of yokes is formed with a continuous resilient seal member loosely extending over the body of the trunnion cross and adapted to contain therein a supply of lubricant located within a recess formed with a center of the recess spaced closer to the axis of symmetry of the trunnion cross than the peripheral portions of the recess. Grooves extend from the trunnion members to the center of the recess, with the grooves being arranged to have an angle of inclination relative to the axis of symmetry of the trunnion cross.
