PROBLEM TO BE SOLVED: To provide a viscose fluid coupling for improving the control accuracy of transmitting torque by accurately controlling the supply amount of silicon oil from a reservoir chamber into an operation chamber. SOLUTION: The viscose fluid coupling comprises a driven shaft 4 arranged coaxially with a timing pulley 3, the reservoir chamber 6 reserving the silicon oil O, a torque transmitting part 7 for transmitting torque from the pulley to the driven shaft depending on the supply amount of the silicon oil O from the reservoir chamber, a fluid passage 8 communicating the reservoir chamber with the operation chamber 12 of the torque transmitting part, and a control mechanism 9 for changing the capacity of the reservoir chamber to control the supply amount of the silicon oil into the operation chamber. Between the reservoir chamber and each of the fluid passage and the torque transmitting part, closed circuits are established by which the silicon oil is sealed in an almost sealed-up condition.
