である。More specifically, the rust-preventive open gear grease of the present invention comprises 55 to 60% by weight of a mineral oil as a base oil and 10% of a hydrophobic silica as a thickener (an action of solidifying and giving a stickiness). A rust-preventive additive selected from oleic acid salts of dicyclohexylamine, naphthalenesulfonic acid, and sorbitan stearate, which are generally known, in an amount of up to 15% by weight and a paraffin for further improving gloss of 5 to 10% by weight. To 1 to 5% by weight of grease,
Extreme pressure additive containing 1 to 5% by weight of extreme pressure additive composed of fatty acid including oleic acid, palmitic acid, stearic acid, etc., 2 to 5% by weight of zinc dialkyldithiophosphate, and 5 to 15% by weight of organic molybdenum (Mo) compound Additive, polybutene 5
The composition has a pour point depressant of 15% by weight.
【００１０】上記ポリブテンの重量％が５重量％以下に
