A blade structure for a torque converter, produced by a process including the steps of: stamping a flat blank into a first annular plate that includes a first connecting ring portion, a second connecting ring portion, and a plurality of blades spaced from each other in a circumferential direction of the first and second connecting ring portions; bending the blades into a curved shape curved with respect to the first annular plate; bending the blades to be inclined by a predetermined angle with respect to the first and second connecting ring portions; and expanding the first annular plate outwardly in a radial direction thereof to thereby form a predetermined annular shape that has a larger radial dimension than the first annular shape and a larger circumferential distance between respective adjacent two of the blades than that in the first annular plate.
