Disclosed is a lubricant composition containing a lubricant base oil, a phosphorus compound and at least one organic acid salt selected from alkaline earth metal sulfonates, alkaline earth metal phenates and alkaline earth metal salicylates, wherein the phosphorus compound content and the organic acid salt content satisfy the conditions (1)-(3) below. Also disclosed is a driving force transmitting system using such a lubricant composition. 0.01 ≤ W(P) ≤ 0.2 (1) 0.01 ≤ W(M) ≤ 0.2 (2) 0.1 ≤ W(P)/W(M) ≤ 10 (3) (In the formulae (1)-(3), W(P) represents the phosphorus compound content in terms of the phosphorus element based on the total amount of the lubricant composition, while W(M) represents the organic acid salt content in terms of the alkaline earth metal element based on the total amount of the lubricant composition. |
