Abstract

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.
