A method of manufacturing an outer retainer for a one-way clutch having an outward flange at one side edge thereof involves punching out a part of an annular portion having the outward flange by sliding a punch toward an axis of the outer retainer substantially in an axially inner direction from a retainer outer periphery-sided curve portion of the outward flange to a retainer inner periphery-sided curve portion thereof in a way that uses a die and the punch.
