A connecting structure of a torque converter and an input shaft for an automatic transmission is provided to prevent the suppression of movement of a turbine in a full load state of an engine by forming obliquely a spline in the same direction with respect to a rotatory direction. A spline(1) is formed between an input shaft(53) and a torque converter. The spline is formed obliquely at a predetermined angle in the same direction with respect to a rotatory direction in order to generate power for shifting a turbine to an input shaft direction in a rotating state. The spline is formed to be lowered in the input shaft direction with respect to a central line in a planar point of view so that frictional force is reduced in the rotating state. The frictional force between a turbine and the input shaft is reduced by the spline when a rotating process is performed in a full load state of an engine.
