A rolling element retainer for a linear guideway, wherein the rolling groove of the connective part of the rolling elements retaining chain is composed of a loaded area and a direction changing area. At either end of the loaded-area retainer is arranged an outward extension for mating with the direction-changing-area retainer. The outward extension extends in the direction of the rolling groove of the loaded-area retainer and abuts against a projection part of the end caps of the rolling element retainer. Therefore, not only the motion stability of the linear guideway is effectively improved, but also the rolling elements can move more smoothly.
