摘要： A torque converter includes a turbine impeller integrally connected to a pump impeller, a side-cover having a boss and covering the turbine impeller, and a turbine shaft extending through the boss and connected to the turbine impeller. A radial bearing and a one-way clutch are disposed axially adjacent to each other between the boss of the side-cover and the turbine shaft. The radial bearing serves to retain the boss and the turbine shaft concentrically, and the one-way clutch connects the turbine shaft and the side-cover to each other, when a back load is applied to the turbine shaft. Therefore, a load received by a clutch element of the one-way clutch such as a sprag between the turbine shaft and the side-cover is equalized. Thus, when a back load is applied to the turbine shaft, a slipping between the turbine impeller and the pump impeller is prevented, thereby providing a good engine brake effect.
