PURPOSE:To obtain the thrust bearing made of resin which has excellent mechanical property, heat resistance and less sliding friction and does not damage engaged parts by a method in which the surface layer of the position sliding on engaged parts is made of the resin sheet with low friction coefficient, and the other position is integrally molded with the material certaining main component resin and reinforcements. CONSTITUTION:In the thrust bearing 21 made of resin, the surface layer 23a sliding on engaged parts 3 is composed of the resin sheet 25 with low friction coefficient, and the other position is composed of the material containing main component resin and reinforcements. This bearing 21 is molded as following. That is, the resin sheet 25 wherein on one surface, easy adhesion treatment is applied, and which has extendable and shrinkable property and low friction coefficient, is arranged in the cavity 31 of a mold 30 so as to place the surface 25a of easy adhesion-treatment inside. Next, the molten resin 26 containing the main component resin and the reinforcements is poured into the inner side of the resin sheet 25 in the cavity 31, and the main component resin and the reinforcements are integrally molded with the resin sheet 25. Consequently, the thrust bearing made of resin which has small sliding resistance, small abrasion wear, and does not damage the engaged parts, and further is fully durable for the transmission of torque at high temperature, is obtained. |
