Abstract

A grease composition for resin lubrication, the grease composition to be applied to a sliding surface made of resin, the grease composition containing: a fluorine-based base oil (a kinematic viscosity at 40° C. of 300 mm/s or higher) and a synthetic hydrocarbon oil as base oils; a fluorine-based thickener, and a lithium soap thickener or a lithium complex soap thickener as thickeners; and a fluorine-based surfactant and an extreme pressure additive as additives; and a resin sliding member (slide switch) having a sliding surface made of resin, the sliding surface provided by application with the grease composition.
