Abstract
A torque converter for a vehicle includes a front cover integrally formed with a boss to which a crank shaft of an engine side is connected, an impeller connected to the front cover to rotate together with the front cover, a turbine disposed facing the impeller, a stator disposed between the impeller and the turbine to convert flow of oil directed from the turbine, a lockup clutch mechanism for directly connecting the engine to the turbine. A blade of the impeller and/or the turbine is provided with inner and outer projections coupled to shell and core of the impeller and/or the turbine. Each of the inner and outer and inner projections includes a base located on a slit formed on the shell/core and an extending section extending from the base, the extending section being bent after penetrating the slit.
