A torque converter including a one-way clutch for supporting a stator radially on a fixed member in such a manner that the stator is rotatable in one direction, and a pair of thrust bearings for supporting the stator axially between a pump impeller and a turbine runner, wherein the diameters of the one-way clutch and both of the thrust bearings are different, and the thrust bearings do not axially overlap at least side bearings of the one-way clutch. With this arrangement, thrust force is not applied to the side bearings, and thus, the side bearings are thinner than conventional side bearings. Accordingly, the area radially inside of the stator in the torque converter is axially shortened.
