A fluid torque converter for a vehicle is provided which comprises a pump wheel connected to an engine output shaft via a drive plate, a turbine wheel connected to a turbine shaft and a one-way, on-off clutch arranged in the space between the drive plate and the turbine wheel. The clutch effects the mechanical transmission of power from the engine output shaft to the turbine shaft. The one-way clutch has an annular driving clutch member with a conical surface connected to the drive plate via an inner plate, and an annular driven clutch member with a conical surface is connected to the turbine wheel via a piston and a spring. A plurality of wedge rollers are disposed and held between the conical surfaces of the driving and driven clutch members.
