To provide a lubricating grease composition used at a sliding part between resin members or between a resin member and a metal member that exhibits both a lubricating function (low dynamic friction coefficient) and a stationary function (high static friction coefficient).
The grease composition used at a sliding part between resin members or between a resin member and a metal member comprises a base oil, a thickening agent and, as a solid lubricant, melamine cyanurate (MCA) or polytetrafluoroethylene (PTFE), where the total compounded amount of MCA and PTFE is within the range of 0.1-25 wt.% based on the whole weight of the grease and the compounding ratio of MCA and PTFE is such that the MCA/PTFE weight ratio is within the range of 0.05-50.
