Abstract

A lubricating grease composition for a resin member is used to be supplied as a lubricant on a surface of at least a sliding portion of a resin member including the sliding portion with an other member. The lubricating grease composition for a resin member contains a base oil which is a mixed oil of a poly-α-olefin having a kinetic viscosity at 40° C. of 18 to 50 mm/s and an ethylene-α-olefin copolymer having a number average molecular weight of 40,000 to 200,000, a lithium-based complex soap as a thickener and a polytetrafluoroethylene resin as a solid lubricant having a mixing ratio of 4 to 12 mass % to the entire lubricating grease composition, wherein the base oil has a kinetic viscosity at 40° C. of 80 to 200 mm/s and a worked penetration of the lubricating grease composition ranges from 265 to 340.
