    摘要: A resin snap cage 4 comprises a resin-made circular main part 10, a plurality of pockets 11 provided in one axial end face of the circular main part 10, and a circular reinforcing member 12 installed concentrically at the other end face in an axial direction of the circular main part 10. While this reinforcing member 12 is circular along the circular main part 10, a sectional shape in a plane parallel to an axial direction is a rectangle. The reinforcing member 12 is embedded in a recessed portion formed at the other end face in an axial direction of the circular main part 10 to be integrated, an outside diameter surface 12a, an inside diameter surface 12b, and a pocket-side surface 12c of the reinforcing member 12 are covered with the circular main part 10, and a surface 12d thereof opposite to the pocket side is exposed. This resin snap cage 4 is produced by insert molding where the reinforcing member 12 is made as an insert, and the circular main part 10 and the reinforcing member 12 are integrated at the time of the insert molding.
