ABSTRACT:
A fluid power transmission which comprises: a pump impeller; a turbine runner; a housing accommodating the pump impeller and the turbine runner; a lock-up clutch adapted to be engaged with and released from a front cover integrated with the pump impeller; and a viscous coupling including an annular drive member and an annular driven member for transmitting torque inbetween through viscous fluid. The drive member is connected to the lock-up clutch, whereas the driven member is connected to a hub which is integrated with the turbine runner. Further comprised is a second clutch which is engaged, after the lock-up clutch has been engaged, to connect the drive member and the driven member mechanically.
