Abstract
A resin snap cagecomprises a resin-made circular main part, a plurality of pocketsprovided in one axial end face of the circular main part, and a circular reinforcing memberinstalled concentrically at the other end face in an axial direction of the circular main part. While this reinforcing memberis circular along the circular main part, a sectional shape in a plane parallel to an axial direction is a rectangle. The reinforcing memberis embedded in a recessed portion formed at the other end face in an axial direction of the circular main partto be integrated, an outside diameter surface, an inside diameter surface, and a pocket-side surfaceof the reinforcing memberare covered with the circular main part, and a surfacethereof opposite to the pocket side is exposed. This resin snap cageis produced by insert molding where the reinforcing memberis made as an insert, and the circular main partand the reinforcing memberare integrated at the time of the insert molding.
