Claims

[Scope of utility model registration request]

It has a pump connected to the output shaft of the engine, a turbine rotationally driven by the pump via fluid, and a stator supported between the pump and the turbine via a one-way clutch to increase torque. 1. A structure of an automatic transmission equipped with a torque converter, characterized in that the automatic transmission is provided with rotational driving means for rotationally driving the stator in the same direction as the pump when the one-way clutch is in a locked state.
