Abstract
A method of forming a driven plate (20) of a torque converter (1) has first, second and third steps. In the first step, a flat plate member (10) is cut into a predetermined configuration. In the second step, the plate member (10) is wound to form an annular member 11 that has slightly overlapping ends with a predetermined length (t). In the third step, resistance welding is performed on overlapping ends of the annular member (11), and thereby the opposite end portions are joined together to form a continuous annular member (12).
