To shorten a size of a thrust washer for a high speed and high surface pressure slide in an axial direction and to reduce in a weight by satisfying all of a wear resistance, low frictional coefficient and required rigidity.
The thrust washer for a high speed and high surface pressure slide is formed of a resin composition containing 10 to 80 pts.wt. of carbon fiber and 2 to 50 pts.wt. of perflurofluororesin such as a polytetrafluoroethylene resin or the like to 100 pts.wt. of polyallylene sulfide resin such as polyphenylene sulfide resin or the like. The washer may be formed of a resin composition mixed with 1 to 30 pts.wt. of a molybdenum compound. In the case of manufacturing a thrust washer for a high speed and high surface pressure slide having an oil hole formed to penetrate a groove communicating with an outer periphery from an inner periphery of an annular washer or front and rear surfaces of a thrust washer, a sprue is disposed on an inner or outer periphery of a mold to injection mold.
