摘要： A method for manufacturing a metal part and a sheet pressing wheel, in which reduction of their manufacturing cost is intended by enabling them to be formed only by plastic work such as press-work even if they are very small; and a printer in which such wheels are incorporated as a sheet feed mechanism. In the method for manufacturing a metal part, plastic work is given to a metal plate to thereby manufacture the metal part. The method for manufacturing a metal part comprises a first forming step for performing a punching work for roughly forming at least a part of the outline shape of the metal part; a second forming step for giving a face-pressing work to at least an outline edge portion of the metal part to thereby thin the outline edge portion; and a third forming step for shaping the outline shape again by a punching work.
