A resin composition which comprises about 40 to about 95% by weight of a heat-resistant resin having a heat deformation temperature of 100.degree. C. or higher under a stress of 1,820 KPa defined by ASTM D-648 and about 60 to about 5% by weight of spherical glass beads having an average particle diameter of about 10 to about 500 .mu.m, or which comprises about 40 to about 90% by weight of a heat-resistant resin having a heat deformation temperature of 100.degree. C. or higher under a stress of 1, 820 KPa defined by ASTM D-648, about 55 to about 5% by weight of spherical glass beads having an average particle diameter of about 10 to about 500 .mu.m and about 55 to about 5% by weight of a solid lubricant, is used as a suitable molding material for sliding members to be used at contact parts with a soft metal member, and when molded into seal rings in sliding contact with an aluminum alloy rotary shaft of an automatic transmission cylinder, not only wear coefficient of mate material and also self wear coefficient can be considerably lowered, but also a good working oil sealability can be effectively obtained.

Resin composition

A molding compound which comprises phenol resin or polyphenylenesulfide resin, chopped strands of glass fibers and powdery glass fibers having a length of about 10 to about 200 .mu.m is used suitably for molding a resin stator having an insert molded or post-inserted metallic outer race.
