PURPOSE:To make the start of a turbine ever so smooth, by installing a centrifugal lockup clutch, frictionally engaging the pump side in time of dead slow, in the side of the turbine of a hydraulic coupling. CONSTITUTION:A drive plate 2 at the end part of a crankshaft 1 is locked to the side of a cover member 5 being solidly installed together with a pump 4 of a hydraulic coupling 3. A centrifugal lockup clutch 7 is coupled with a turbine 6 of the hydraulic coupling 3, and when a revolving speed of the turbine 6 becomes more than the specified one, it frictionally engages the cover member 5. Therefore, not only smooth starting is performable but also lockup clutch is able to automatically operate owing to centrifugal force, thereby dispensing with control over hydraulic pressure or the like utterly. |
