<p>In a torque converter (1) comprised of three major rotating elements, namely a pump impeller (11) formed integral with a converter cover (6), a turbine runner (12) to which a driving power is transmitted through a working fluid from the pump impeller (11), and a stator (15) disposed between the pump impeller (11) and the turbine runner (12), the stator (15) is supported on a transmission case via a one-way clutch (14) 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. <IMAGE></p> |
