    摘要： A traction fluid which is prepared by compounding a diester represented by general formula (I) (wherein A' represents an ester bond of -COO- or -OOC-, n represents 1 to 10, R1 groups represent one or two members selected from among a hydrogen atom and an alkyl group having 1 to 8 carbon atoms, and R2 groups represent one or two members selected from among a hydrogen atom and an alkyl group having 1 to 3 carbon atoms) or its derivative is disclosed. This fluid is preferably used in a power transmission unit, particularly a traction drive unit.

    摘要： The invention addresses a problem of providing a lubricating oil composition which is superior in cooling performance, ensures electrical insulation and has a high flash point. The problem is solved by a lubricating oil composition containing a base oil (A), wherein the base oil (A) contains an ester-based synthetic oil (A1), the content of the ester-based synthetic oil (A1) is 30% by mass to 100% by mass based on the total amount of the base oil (A), the ester-based synthetic oil (A1) is one or more selected from the group consisting of an ester (A1-1) of a monohydric alcohol and a monobasic acid and an ester (A1-2) of a monohydric alcohol and a polybasic acid, and the base oil (A) satisfies the following requirements (1) to (3): Requirement (1): the kinematic viscosity at 40°C is 2.00 mm 2 /s to 4.00 mm 2 /s. Requirement (2): the specific heat at 20°C is 1.75 kJ/(kg ·K) or less. Requirement (3): the density at 20°C is 0.850 g/cm 3 or more.
