1. A multifunctional lubricant composition, comprising, with respect to 100 parts by mass of phosphorus compound (A) represented by the following general formula (1), 26 parts by mass to 43 parts by mass of phosphorus compound (B) represented by the following general formula (2), 0 parts by mass to 1.3 parts by mass of phosphorus compound (C) represented by the following general formula (3), and a total of 0 parts by mass to 1.3 parts by mass of triphenyl phosphate and tricresyl phosphate: where R1 represents a hydrocarbon group having 1 to 10 carbon atoms, R2 represents a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms, and R3 and R4 each independently represent a hydrogen atom or a methyl group, provided that when R1 represents a methyl group, R2 does not represent a hydrogen atom; where R5 and R7 each independently represent a hydrocarbon group having 1 to 10 carbon atoms, R6 and R8 each independently represent a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms, and R9 represents a hydrogen atom or a methyl group, provided that when R5 represents a methyl group, R6 does not represent a hydrogen atom, and that when R7 represents a methyl group, R8 does not represent a hydrogen atom; where R10, R12, and R14 each independently represent a hydrocarbon group having 1 to 10 carbon atoms, and R13, and R15 each independently represent a hydrogen atom or a methyl group, provided that when R10 represents a methyl group, does not represent a hydrogen atom, that when R12 represents a methyl group, R13 does not represent a hydrogen atom, and that when R14 represents a methyl group, R15 does not represent a hydrogen atom. |
