A thrust plate utilized between the end face of a bearing pin of a trunnion in a universal joint and the bottom wall of a bushing on the bearing pin is formed of a wear-resistant heat-stable plastic material and lubricant grooves are formed in at least one surface of the plate. A plurality of protuberances which may be in the form of honeycombs, cams, or cam-ridges are formed in a surface of the plate between the lubricant grooves and occupy an area such that the deformation resistance under compression load will be less than two-thirds of the corresponding resistance value for the plate.
