Abstract
In a viscous fluid coupling which is essentially composed by one rotor, the other rotor, a first oil storage chamber and a valve, the one rotor fixed to an input member and the other rotor fixed to an output member are combined to form an operation chamber. The first oil storage chamber is formed between the other rotor and the output member, and the valve opens and closes a port of an oil passage which communicates the first oil storage chamber with the operation chamber under control of a temperature sensitive member attached to the output member. In this construction a case fixed to the output member covers a side surface opposite to the rotors. A second oil storage member is disposed in a position corresponding to the first oil storage chamber between one rotor and the case. With this arrangement, a so-called taking-around phenomenon which is present when the operation of the viscous fluid coupling resumes can be eliminated.
