ABSTRACT:
A torque converter includes at least two thrust bearings disposed on respective axially-opposite sides of a radially-inward portion of a stator. The stator includes a non-rotatable member, a rotatable member, and a one-way clutch. The rotatable member has a cylindrical portion having an inner peripheral surface interlocked with the one-way clutch, and an extension portion which extends from an approximately axially-central region of the cylindrical portion in a radially-outward direction relative to the cylindrical portion, and has an axial thickness less than that of the cylindrical portion. The thrust bearings are disposed to clamp the extension portion from respective axially-opposite sides of the extension portion at respective positions located radially outwardly relative to the cylindrical portion, so as to facilitate reduction in axial dimension of the torque converter.
