<p>A blade structure (11) for a torque converter (1), produced by a process including the steps of: stamping a flat blank into a first annular plate that includes a first connecting ring portion (14), a second connecting ring portion (16), and a plurality of blades (12) 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.</p> |
