The use of resin for such a thrust bearing is possible because the sliding properties of resin in oil are good with respect to a metal counterpart (sleeve 3). However, since resin has inferior mechanical strength and heat resistance compared to metal, it is necessary to strengthen it. Therefore, conventionally, reinforcing materials such as glass fiber and asbestos have been mixed into the resin.

When a thrust bearing is molded by mixing reinforcing material with resin as described above, the reinforcing material is exposed on the sliding surface that slides against the mating part, increasing the coefficient of friction and making it more aggressive towards the mating part. This not only increases the sliding resistance between the parts, but also damages the mating material.

Next, as shown in FIG. 3, the mold 30 is closed, and molten resin 26 containing a reinforcing material is filled into the cavity 31 through the injection port 32 in the same manner as in a normal molding method. The resin 26 is a phenolic resin mixed with 35% glass fiber and 1% by weight. Since the resin sheet 25 is stretchable and has been softened by being heated by the mold 30, when it is pressed against the inner wall 31a of the cavity 31 by the injection pressure of the resin 26, it stretches to follow the shape. Since the molten resin 26 side of the surface of the resin sheet 251 is treated to facilitate adhesion, the resin sheet 25 is integrally molded with the resin 26 and forms the surface layer 23a of the thrust bearing 21.
