Claims

[Claims for Utility Model Registration] 1. A sealed case that is relatively rotatably supported on a rotary drive shaft with a drive disk fixed to its tip, and a sealed case that surrounds the drive disk and contains a viscous fluid. A hydraulic coupling device of the type that transmits torque by interposing a viscous fluid in the gap between the wall surface of the drive disk and the inner wall surface of the sealed case, the coupling device comprising: casings are spaced apart from each other, a cooling chamber for accommodating a cooling medium is formed between the casings and the sealed case, and the casings are connected to the rotary drive shaft so as to be rotatable at substantially the same speed. Characteristic fluid coupling device. 2. The device according to claim 1, wherein the casing is connected to the rotary drive shaft via a magnetic coupling. 3. The device according to claim 1, wherein the casing is fixed on the rotational drive shaft. 4. The device according to claim 1, which is a registered utility model, wherein fins are protruded along the circumferential direction from the inner surface of the casing forming the wall surface of the cooling chamber. 5. The device according to claim 1, wherein the casing has fins protruding from its outer surface.
