A torque converter for a vehicle includes a front cover, an impeller configured to rotate and being coupled to the front cover, a turbine disposed to face the impeller, a turbine shell provided in the turbine, a stator disposed between the impeller and the turbine, and a lockup clutch provided with a drive hub connected to the front cover. The lock-up clutch has a drive disc provided in the drive hub, a driven disc coaxially disposed to the drive disc, and a driven hub provided with the driven disc, and a torsional damper comprising a retaining plate disposed between the lock-up clutch and the turbine. Engine torque is transmitted to the retaining plate through the front cover by a frictional contact between the drive disc and the driven disc.
