    摘要: Provided is a method of manufacturing a resin retainer having two annular sections. A fixed-side cavity forming mold has a first axial mold surface that is in contact with an axial end surface of a first annular section of the annular sections of a resin retainer having two annular sections, and a first protruding portion protruding from the first axial mold surface. A movable-side cavity forming mold has a second axial mold surface that is in contact with an axial end surface of a second annular section of the annular sections of the resin retainer, and a second protruding portion protruding from the second axial mold surface. A slide core sliding step is performed in which slide cores are slid toward an outer diameter and pocket-forming protruding portions of the slide cores are extracted from a pocket of the retainer, and then a mold opening step is performed in which the movable-side cavity forming mold is opened relative to the fixed-side cavity forming mold.
