An object of the present invention is to provide a grease composition for resin lubrication which is capable of keeping good the sliding lubrication between a resin member and a-metal member, and between a metal member and another metal member over the long term. The present invention provides a grease composition for resin composition which is characterized by including a base, a thickener, and at least one of a nonpolar wax and a polar wax. Further, the grease composition for resin lubrication is applied to a telescopic shaft for vehicle steering or an electric power steering apparatus, thereby to improve the durability, and to achieve a longer life.
