The present invention provides a lubricating oil composition for transmissions which is improved in fuel saving properties and has excellent metal fatigue prevention properties and heat resistance. The lubricating oil composition comprises (A) a mineral base oil having a 100° C. kinematic viscosity of 1.5 mm 2 /s or higher and 3.5 mm 2 /s or lower, a pour point of −25° C. or lower, a viscosity index of 110 or greater, a % C N of 2 or greater and 20 or less and a % C A of 3 or less, the lubricating oil composition having a 100° C. kinematic viscosity of 2.5 mm 2 /s or higher and 3.8 mm 2 /s or lower. |
