There is provided lubricants for power transmission which exhibit not only a high coefficient of traction but also a high flash point. The lubricants for power transmission according to the present invention contains an alicyclic alcohol carboxylic diester compound represented by the general formula (1):
R
1
—CO—O—(X
1
)
m
-Z-(X
2
)
n
—O—CO—R
2
(1)
wherein Z is a cycloalkylene group having 3 to 12 carbon atoms; R
1
and R
2
are each independently a chain hydrocarbon group having 3 to 20 carbon atoms; X
1
and X
2
are each independently a linear or branched alkylene group having 1 to 5 carbon atoms; and m and n are respectively an integer of 0 or 1.
