The present invention provides a swash plate, for a swash plate compressor, which is excellent in a resistance to the occurrence of seizing in a condition where an extreme pressure is generated owing to local contact between the swash plate and a shoe which slides thereon and in a condition where lubricating oil is depleted, capable of preventing cavitation-caused erosion of a resin film when the swash plate is operated at a high surface pressure and a high speed in the presence of the lubricating oil and the swash plate compressor having the swash plate. A swash plate ( 3 ) for a swash plate compressor is so constructed that inside a housing ( 1 ) where a refrigerant is present, the refrigerant is compressed and expanded by converting a rotational motion of the swash plate ( 3 ) mounted perpendicularly and obliquely on a rotational shaft ( 2 ) by directly fixing the swash plate ( 3 ) to the rotational shaft ( 2 ) or indirectly fixing the swash plate ( 3 ) to the rotational shaft ( 2 ) through a coupling member into a reciprocating motion of a piston ( 5 ) through a shoe ( 4 ) which slides on the swash plate ( 3 ) into a reciprocating motion of a piston ( 5 ) through a shoe ( 4 ) which slides on the swash plate ( 3 ). A resin film containing 25 to 70 parts by weight of fluororesin and 1 to 20 parts by weight of graphite for 100 parts by weight of matrix resin and having a tensile shear adhesive strength not less than 25 MPa is formed on a sliding contact surface of the swash plate ( 3 ) on which the shoe ( 4 ) slides.

A lubricating grease composition for a polyamide resin member is used to be supplied as a lubricant on a surface of at least a sliding portion of the polyamide resin member including the sliding portion with an other member. The lubricating grease composition for a polyamide resin member contains a base oil which is a synthetic hydrocarbon oil, and a thickener which is at least one metal complex soap of a barium complex soap and a lithium complex soap, wherein a kinetic viscosity at 40° C. of the base oil ranges from 30 to 200 mm/s and a drop point of the thickener is 270° C. or more. 2. The lubricating grease composition for a polyamide resin member according to claim 1 , wherein the base oil is a single oil of a poly-α-olefin or a mixed oil of the poly-α-olefin and an ethylene-α-olefin copolymer.3. The lubricating grease composition for a polyamide resin member according to claim 1 , wherein the other member is a metal member. The present application is a continuation application of International Patent Application No. PCT/JP2016/054892 filed on Feb. 19, 2016, which claims priority to Japanese Patent Application No. 2015-066850, filed on Mar. 27, 2015. The contents of these applications are incorporated herein by reference in their entirety.The present disclosure relates to a lubricating grease composition for a polyamide resin member used to be supplied as a lubricant on the surface of at least a sliding portion of a polyamide resin member including the sliding portion where, for example, the other member comprising a resin member or a metal material slides or which slides on the other member.Heretofore, greases have been used as lubricant compositions in various industrial fields such as steels, automobiles, general machineries, and precision instruments. In recent years, polyamide resins have been commonly used as the member for sliding portions, and the like, of automobile parts, and the like, for the purpose of improving heat resistance in light of being used ...
