A retainer particularly suitable for use in a crossed-roller rolling contact bearing assembly is provided. The retainer is comprised of a thin plate which is provided with at least one hole for locating therein a roller. A pair of top and bottom projections are formed in the hole for providing main contact surfaces for holding the roller in position by surface contact. Additionally, the wall which defines the hole is provided with a double-tapered section at least partly, and this double-tapered wall section provides auxiliary contact surfaces for holding the roller in position by surface contact.
