Abstract
In a torque converter provided with a lockup device, performance of a torsion spring is improved, preferably by increasing its size, while suppressing an increase of an axial dimension of the torque converter. The torque converter includes a toric fluid actuating portion having an impeller, a turbine, and a stator. A ratio (D /D ) of an inside diameter D to an outside diameter D of the fluid actuating portion is equal to or greater than 0.61.
