Abstract:
A torque converter comprising a pump impeller connected to an input shaft, and a turbine impeller which is opposed to said pump impeller and to which a turbine shaft is connected, wherein said torque converter further includes a radial bearing and a one-way clutch, which are disposed coaxially adjacent to each other between a boss of a side-cover integrally connected to said pump impeller to cover said turbine impeller and said turbine shaft extending through said boss and connected to said turbine impeller, said radial bearing serving to retain said boss and said turbine shaft concentrically, and said one-way clutch connecting said turbine shaft and said radial bearing to each other when a back load is applied to said turbine shaft, wherein said radial bearing is axially non-movably mounted on said boss of said side-cover, and a boss of said pump impeller is secured to said input shaft, so that a thrust load applied to an output gear which is connected to an outer end of said turbine shaft in a direction toward said turbine impeller is applied to said radial bearing.
