Abstract
In a torque converter comprised of three major rotating elements, namely a pump impeller formed integral with a converter cover, a turbine runner to which a driving power is transmitted through a working fluid from the pump impeller, and a stator disposed between the pump impeller and the turbine runner, the stator is supported on a transmission case via a one-way clutch and has a plurality of stator blades. In order to balance the enhanced vehicle's startability and improved fuel economy at idle, the ratio W/D of a stator-blade axial length W to a torque-converter nominal diameter D is set to satisfy a predetermined inequality 0.030≦W/D≦0.052.
