PURPOSE: To obtain the subject fluid useful as an actuator for vibration absorption, torque transmission, etc., having excellent stability at a low temperature without causing phase separation even by leaving it to stand for a long period of time, change in temperature and impression of voltage, comprising a mixture of a specific liquid crystal compound and an aromatic oil. CONSTITUTION: This fluid comprises a mixture of (A) a liquid crystal compound [e.g. a liquid crystal compound of the formula ((m) and (n) are those that m+n is 30 and m/n is 1, 4 on the average, respectively] obtained by bonding plural liquid crystal groups to one molecular chain directly or through a space such as a bond chain of the formula (SiR<1> R<2> O) (R<1> and R<2> are each an alkyl or phenyl) and (B) an aromatic oil which does not show liquid crystal properties by itself and provides a mixed solution having liquid crystal properties when mixed with the component A. The component B contains >=10% aromatic carbon in ring analysis and comprises two or more aromatic oils. |
