(57) Abstract: To provide a traction drive fluid having a high traction coefficient in a wide temperature range. SOLUTION: The general formula: (In the formula, R 1 to R 10 may be independently selected from hydrogen or a C 1 to C 3 alkyl group or a cyclohexyl group, and Q 1 to Q 4 may be selected from a C 1 to C 3 alkyl group or a cyclohexyl group. N 1 to n 4 each independently selected, and n 1 to n 4 represents an integer of 0 to 5) as the component (A), and cyclopentadiene and vinyl aromatic hydrocarbons. A fluid for traction drive, which comprises as a component (B) a thermal copolymer or a hydride thereof having a softening point of 40 ° C. or higher or a weight average molecular weight of 250 or higher. |
