Abstract: PURPOSE:To reduce a flowing loss by installing a run-off part, avoiding any interference with a blade, in a part to be opposed to the blade of a turbine runner on the outer circumferential surface of a stator blade part, and forming this part into a curved surface where two directional sections orthogonal with each other are composed of a curve. CONSTITUTION:Oil in a torque converter 10 is fed in by a pump impeller 12 from the circumferential side of a turbine runner 14, imparting turning force to a blade 14a, and then it flows into a stator 16, flowing into the pump impeller 12 agains, and thereby transmission of the turning force is carried out between the pump impeller 12 and the turbine runner 14. When oil flows into the stator 16 from the turbine runner 14, this oil flows along a blade form of the stator 16, and since a blade tip side forms a smooth curved surface at the center of the blade form and the inner circumferential side part, a smooth oil flow is actualized, and even concerning a run-off part 16a, the blade form tip side is formed by a smooth curved surface, so that a smooth flow of oil is thus realized. With this constitution, a flowing loss due to an oil collision is decreased, and transmission efficiency is well improved.
