A gear oil composition for a manual transmission capable of increasing the coefficient of friction between a synchronizer ring and a gear cone, stabilizing the coefficient of friction to improve the synchronizer operability, and preventing the wear of the synchronizer ring. To provide. A gear oil composition for a manual transmission according to the present invention comprises (A) a base oil having a kinematic viscosity at 100 ° C. of 1 mm 2 / s to 35 mm 2 / s, and (B) a molybdenum compound. Thus, the blending amount of the component (B) is 50 mass ppm or more and 300 mass ppm or less in terms of molybdenum element. [Selection figure] None |
