PROBLEM TO BE SOLVED: To simplify structure so as to reduce cost, attain stability of operation by disposing a solenoid valve appropriately and prevent early degradation of a bearing and the like so as to attain a long service life. SOLUTION: A driving disc fixed to a rotary shaft l is accommodated in a sealed case 2 rotatable around the rotary shaft 1. A torque transmission chamber 4 and an oil feeding chamber 6 are provided through a partition plate 5 in the sealed case 2, and the driving torque of the driving disc 3 is transmitted to the sealed case 2 by oil fed to the torque transmission chamber 4 from the oil feeding chamber 6. In a liquid clutch of such constitution, a passage control solenoid valve 10 is disposed coaxially with the rotary shaft 1 at an intermediate part of a discharge passage 7 for feeding oil, recovered by dam mechanism, to the oil feeding chamber 6 from the torque transmission chamber 4. |
